I don't see anyone lay out how this proposal can interact with nested types and such. There's a fair amount of complexity in Swift with what you can do by nesting things inside of each other, so the simple conceptual model of "locals are unqualified, instance variables have a self. prefix" doesn't seem to generalize.<br>
<br>
Will I need to qualify associated types with the protocol or type name to refer to them? What about generic type parameters, they're sort of like "instance variables" too.<br>
<br>
What about class methods that want to call each other? Do they need the explicit 'self', or an explicit class name prefix? The latter changes semantics if the class method is overridden in a subclass.<br>
<br>
If we ever add the ability for an inner type to capture stored properties from the outer type, how do you reference properties of the outer type? I guess the problem has to be solved anyway to refer to an outer "self" explicitly, but qualifying everything with OuterType.self.foo kind of defeats the purpose of inner types altogether.<br>
<br>
I'm not sure I buy the readability arguments in favor of this approach. It seems the languages where explicit 'self' was adopted did it mostly by accident, or because of implementation concerns. In Python for instance, there's no way for assignment to modify a binding in an outer scope, so 'foo = bar' always sets a local named 'foo', IIRC. So explicit self is needed there. Greg Parker explains earlier in this thread by explicit self was chosen for Objective-C, and it wasn't readability.<br>
