[swift-evolution] [Pitch] Requiring proactive overrides for default protocol implementations.

[Jérôme ALVES]

What if... 

FooBar.framework defines :
public protocol A {
    func foo()
}
public type B: A {
    public func foo () { 
          … implementation … 
    }
}

Other module defines :
import FooBar
extension A {
    func foo() { .. default implementation … }
}
