Some fun with swift

pipe.swift

// Pipe operator
operator infix | {
    associativity left
}

// Use the left side as a parameter for the function on the right.
func |<T, R>(left:T, right:(T) -> (R) ) -> R { return right(left) }

var upperCase:(String) -> (String) = { $0.uppercaseString }

// Pipe "test" through upperCase
"test" | upperCase



// Use a curried Function
func incrementGenerator(by:Int)(inc:Int) -> (Int){
    return inc + by;
}

var incBy5 = incrementGenerator(5);

5 | incBy5 | incBy5
