Might as well just drop the var keyword altogether at that point. func foo(x: int, y: int): int { sum : int = x + y return x + y } With type inference the type declaration just collapses out to what you have now. func foo(x: int, y: int): int { sum := x + y return x + y } I've seen it in a few languages and it has seemed quite nice in use and appearance to me.
