- Makes `Self` a keyword
- Inside `class Foo { `... `}`, `Self` means `Foo`
- Inside `class Foo(T:! Type, U:! Type) {` ...` }`, `Self` means `Foo(T, U)`
- `impl as Bar` means `impl Self as Bar`
- Inside `external impl Foo as Bar {`...`}`, not in a scope already defining `Self`, `Self` means `Foo`
Implemented by introducing a new kind of declaration, a `SelfDeclaration`, that is automatically added to class and impl declarations.
