Swift ++ operator
Raw
CSwift.swift
prefix func ++(inout x: Int) -> Int {
x = x + 1
return x
}
postfix func ++(inout x: Int) -> Int {
let oldX = x
x = x + 1
return oldX
}

It works like a charm. But just have a problem for postfix operation i.e. **WARNING: Result of operator ++ is unused.** Any solution to avoid that warning?

Snippet:

var i = 0
print("Value of i : \(i++)")
i++ // **WARNING: Result of operator ++ is unused**
print("Value of i : \(++i)")

P.S.
I don't want to replace i++ with _ = i++ to just ignore waring.
