Disambiguating methods with external parameter names

playground.swift

import Cocoa

func curry<A, B, C> ( f: (A, B) -> C ) -> (A -> B -> C) {
    return { x in
        return { y in
            return f(x, y)
        }
    }
}

func add(a: Int, b: Int) -> Int {
    return a + b
}


class Foo {
    func add(a: Int, b: Int) -> Int {
        return a + b
    }
    
    func myAdd(a: Int, b: Int) -> Int {
        return a + b
    }
    
    func myAdd(a: Int, doubling b: Int) -> Int {
        return a + 2*b
    }
}


let foo = Foo()



let add2 = curry(add)(2)
add2(5) // 7

let boundAdd2 = curry(foo.add)(2)
boundAdd2(4) // 6

let myAdd2 = curry(foo.myAdd)(2)   // Error: ambiguous use of 'myAdd'
let myDoubledAdd2(foo.myAdd(doubling:))(2) // Error: consecutive statements on a line must be separated by ';'

IIRC Xcode 6.3 beta has mentioned something about curried function with external parameter name. Have you tried this on 6.3 yet?

Looks like this doesn't work on 6.3 beta too.
