**IDE:** _Visual Studio X/Fire_  
**Version:** _10.0.0.2415 (develop)_  
**Target** (If relevant): _OSX_  
**Description** :  
The parser rejects some constructs involving `Self` (in a protocol extension).

**Expected Behavior** :  
Compiles?  
**Actual Behavior** :  
Parser Errors  
**Steps** :

```auto
protocol Foo {
	static func foo()
}

protocol RR {
  associatedtype RawValue: Foo
  init?(rawValue: RawValue)
}

extension RR {
  public static func foo() { // E1 closing bracket expected, got "Self"
	Self.RawValue.foo()
  }

  public static func bar() {
	var innerResult: Self.RawValue?
	innerResult.flatMap { Self(rawValue: $0) } // E1 closing bracket expected, got "Self"
											   // E484 Cannot access members on wrapped nullable type "RawValue?"
											   // E44 No member "flatMap " on type "RawValue"
  }
}

```
