+# Fix for Private Properties in Template Region (#21007)
+
+## Summary
+
+This fix enables access to private class properties (fields and methods) from within the `<template>` region of Glimmer components.
+
+## Problem
+
+Previously, when trying to use private properties in templates like this:
+
+```javascript
+import Component from '@glimmer/component';
+import { tracked } from '@glimmer/tracking';
+import { on } from '@ember/modifier';
+
+export default class HelloWorld extends Component {
+  @tracked count = 0;
+
+  #increment = () => this.count += 1;
+
+  <template>
+    <p>You have clicked the button {{this.count}} times.</p>
+    <button type="button" {{on "click" this.#increment}}>Click</button>
+  </template>
+}
+```
+
+The compiler would:
+1. Replace `this.#increment` with `undefined` silently
+2. When used with modifiers, cause runtime errors: `can't access property "bind", userProvidedCallback is undefined`
+3. When used in interpolation (`{{this.#foo}}`), render `undefined` without any warning
+
+## Root Cause
+
+The issue was in `/packages/@ember/template-compiler/lib/compile-options.ts` in the `inScope()` function:
+
+1. The regex `IDENT` checked if a variable name was a valid JavaScript identifier
+2. Private fields (starting with `#`) are not considered regular identifiers by this regex
+3. The function tried to evaluate `typeof #fieldName`, which is invalid JavaScript syntax for private fields
+4. This caused the compiler to treat private fields as "not in scope" and replace them with `undefined`
+
+## Solution
+
+The fix adds support for private field identifiers in the template compiler:
+
+### 1. Added Private Identifier Regex
+
+```typescript
+// https://tc39.es/ecma262/#prod-PrivateIdentifier
+const PRIVATE_IDENT = /^#[\p{ID_Start}$_][\p{ID_Continue}$_\u200C\u200D]*$/u;
+```
+
+### 2. Updated `inScope()` Function
+
+```typescript
+function inScope(variable: string, evaluator: Evaluator): boolean {
+  // Check if it's a private field syntax
+  if (PRIVATE_IDENT.exec(variable)) {
+    // Private fields are always considered "in scope" when referenced in a template
+    // since they are class members, not lexical variables. The actual access check
+    // will happen at runtime when the template accesses `this.#fieldName`.
+    return true;
+  }
+  
+  // ... rest of the function
+}
+```
+
+### 3. Updated Documentation
+
+Updated the documentation in `/packages/@ember/template-compiler/lib/template.ts` to:
+- Indicate that private fields are now supported
+- Provide examples of using private fields in templates
+- Clarify that the `eval` option can handle private field identifiers
+
+## Changes Made
+
+### Files Modified:
+
+1. **`/packages/@ember/template-compiler/lib/compile-options.ts`**
+   - Added `PRIVATE_IDENT` regex constant
+   - Modified `inScope()` function to recognize and handle private fields
+   - Private fields are now treated as always in scope (as they're class members)
+
+2. **`/packages/@ember/template-compiler/lib/template.ts`**
+   - Updated documentation for `ImplicitClassOptions` to show private field support
+   - Added example code demonstrating private field usage
+   - Updated technical requirements section to mention private field identifiers
+
+3. **`/packages/@ember/-internals/glimmer/tests/integration/components/runtime-template-compiler-implicit-test.ts`**
+   - Added test: `@test Can access private fields in templates`
+   - Added test: `@test Private field methods work with on modifier`
+
+## How It Works
+
+Private fields in JavaScript are class members, not lexical variables. When the template compiler encounters a private field reference like `this.#increment`:
+
+1. The compiler recognizes it as a private field using the `PRIVATE_IDENT` regex
+2. It treats the field as "in scope" (returns `true` from `inScope()`)
+3. The field reference is passed through to the compiled template
+4. At runtime, the template accesses the private field on the component instance
+5. Normal JavaScript private field access rules apply (TypeError if accessed from wrong context)
+
+## Testing
+
+Added two new test cases to verify:
+1. Private fields can be accessed in template interpolations
+2. Private methods work correctly with modifiers like `{{on}}`
+
+## Impact
+
+This fix:
+- ✅ Enables use of private fields in templates (resolves #21007)
+- ✅ Maintains backward compatibility (no breaking changes)
+- ✅ Follows JavaScript private field semantics
+- ✅ Works with both the implicit `eval()` form and explicit `scope()` form
+- ✅ Provides better encapsulation for component internals
+
+## Example Usage
+
+### Private Field
+```javascript
+class MyComponent extends Component {
+  #message = "Hello";
+  
+  <template>
+    <p>{{this.#message}}</p>
+  </template>
+}
+```
+
+### Private Method with Modifier
+```javascript
+class MyComponent extends Component {
+  @tracked count = 0;
+  
+  #increment = () => this.count++;
+  
+  <template>
+    <button {{on "click" this.#increment}}>
+      Count: {{this.count}}
+    </button>
+  </template>
+}
+```
+
+### Private Tracked Field
+```javascript
+class MyComponent extends Component {
+  @tracked #internalState = false;
+  
+  #toggle = () => {
+    this.#internalState = !this.#internalState;
+  };
+  
+  <template>
+    <button {{on "click" this.#toggle}}>
+      {{if this.#internalState "ON" "OFF"}}
+    </button>
+  </template>
+}
+```
+
+## Future Considerations
+
+- The Handlebars/Glimmer parser already supports the `#` character in paths
+- Runtime access control is handled by JavaScript's built-in private field mechanism
+- No additional runtime overhead is introduced
+- The fix is forward-compatible with future ECMAScript changes to private fields

-# Fix for Private Properties in Template Region (#21007)
 
-## Summary
-
-This fix enables access to private class properties (fields and methods) from within the `<template>` region of Glimmer components.
-
-## Problem
-
-Previously, when trying to use private properties in templates like this:
-
-```javascript
-import Component from '@glimmer/component';
-import { tracked } from '@glimmer/tracking';
-import { on } from '@ember/modifier';
-
-export default class HelloWorld extends Component {
-  @tracked count = 0;
-
-  #increment = () => this.count += 1;
-
-  <template>
-    <p>You have clicked the button {{this.count}} times.</p>
-    <button type="button" {{on "click" this.#increment}}>Click</button>
-  </template>
-}
-```
-
-The compiler would:
-1. Replace `this.#increment` with `undefined` silently
-2. When used with modifiers, cause runtime errors: `can't access property "bind", userProvidedCallback is undefined`
-3. When used in interpolation (`{{this.#foo}}`), render `undefined` without any warning
-
-## Root Cause
-
-The issue was in `/packages/@ember/template-compiler/lib/compile-options.ts` in the `inScope()` function:
-
-1. The regex `IDENT` checked if a variable name was a valid JavaScript identifier
-2. Private fields (starting with `#`) are not considered regular identifiers by this regex
-3. The function tried to evaluate `typeof #fieldName`, which is invalid JavaScript syntax for private fields
-4. This caused the compiler to treat private fields as "not in scope" and replace them with `undefined`
-
-## Solution
-
-The fix adds support for private field identifiers in the template compiler:
-
-### 1. Added Private Identifier Regex
-
-```typescript
-// https://tc39.es/ecma262/#prod-PrivateIdentifier
-const PRIVATE_IDENT = /^#[\p{ID_Start}$_][\p{ID_Continue}$_\u200C\u200D]*$/u;
-```
-
-### 2. Updated `inScope()` Function
-
-```typescript
-function inScope(variable: string, evaluator: Evaluator): boolean {
-  // Check if it's a private field syntax
-  if (PRIVATE_IDENT.exec(variable)) {
-    // Private fields are always considered "in scope" when referenced in a template
-    // since they are class members, not lexical variables. The actual access check
-    // will happen at runtime when the template accesses `this.#fieldName`.
-    return true;
-  }
-  
-  // ... rest of the function
-}
-```
-
-### 3. Updated Documentation
-
-Updated the documentation in `/packages/@ember/template-compiler/lib/template.ts` to:
-- Indicate that private fields are now supported
-- Provide examples of using private fields in templates
-- Clarify that the `eval` option can handle private field identifiers
-
-## Changes Made
-
-### Files Modified:
-
-1. **`/packages/@ember/template-compiler/lib/compile-options.ts`**
-   - Added `PRIVATE_IDENT` regex constant
-   - Modified `inScope()` function to recognize and handle private fields
-   - Private fields are now treated as always in scope (as they're class members)
-
-2. **`/packages/@ember/template-compiler/lib/template.ts`**
-   - Updated documentation for `ImplicitClassOptions` to show private field support
-   - Added example code demonstrating private field usage
-   - Updated technical requirements section to mention private field identifiers
-
-3. **`/packages/@ember/-internals/glimmer/tests/integration/components/runtime-template-compiler-implicit-test.ts`**
-   - Added test: `@test Can access private fields in templates`
-   - Added test: `@test Private field methods work with on modifier`
-
-## How It Works
-
-Private fields in JavaScript are class members, not lexical variables. When the template compiler encounters a private field reference like `this.#increment`:
-
-1. The compiler recognizes it as a private field using the `PRIVATE_IDENT` regex
-2. It treats the field as "in scope" (returns `true` from `inScope()`)
-3. The field reference is passed through to the compiled template
-4. At runtime, the template accesses the private field on the component instance
-5. Normal JavaScript private field access rules apply (TypeError if accessed from wrong context)
-
-## Testing
-
-Added two new test cases to verify:
-1. Private fields can be accessed in template interpolations
-2. Private methods work correctly with modifiers like `{{on}}`
-
-## Impact
-
-This fix:
-- ✅ Enables use of private fields in templates (resolves #21007)
-- ✅ Maintains backward compatibility (no breaking changes)
-- ✅ Follows JavaScript private field semantics
-- ✅ Works with both the implicit `eval()` form and explicit `scope()` form
-- ✅ Provides better encapsulation for component internals
-
-## Example Usage
-
-### Private Field
-```javascript
-class MyComponent extends Component {
-  #message = "Hello";
-  
-  <template>
-    <p>{{this.#message}}</p>
-  </template>
-}
-```
-
-### Private Method with Modifier
-```javascript
-class MyComponent extends Component {
-  @tracked count = 0;
-  
-  #increment = () => this.count++;
-  
-  <template>
-    <button {{on "click" this.#increment}}>
-      Count: {{this.count}}
-    </button>
-  </template>
-}
-```
-
-### Private Tracked Field
-```javascript
-class MyComponent extends Component {
-  @tracked #internalState = false;
-  
-  #toggle = () => {
-    this.#internalState = !this.#internalState;
-  };
-  
-  <template>
-    <button {{on "click" this.#toggle}}>
-      {{if this.#internalState "ON" "OFF"}}
-    </button>
-  </template>
-}
-```
-
-## Future Considerations
-
-- The Handlebars/Glimmer parser already supports the `#` character in paths
-- Runtime access control is handled by JavaScript's built-in private field mechanism
-- No additional runtime overhead is introduced
-- The fix is forward-compatible with future ECMAScript changes to private fields
