Default value with the same method signature in protocol

Using Swift
3

There have been discussions about new features that can help resolve this issue. Maybe you can revive this thread on evolution. Basically, if you could use a different name when implementing a protocol, the issue would not come up:

protocol A {
    func something()
}
class Test {
    func something(value: Bool = true) {
        print("method")
    }
}
extension Test: A {
    func somethingOfA() as A.something  { // Not valid syntax now
        print("protocol")
    }
}

let test = Test()
let a: A = Test()
test.something()   // method
test.somethingOfA() // protocol
(test as A).something()   // protocol
a.something() // protocol
