[swift-users] Amusing function return warning in swift 3

[Marco S Hyman via swift-users]

My first try with 5/31 swift 3 snapshot gave me a warning regarding an unused 
return value -- in main.swift.   Wouldn’t you know, NS ApplicationMain is 
declared as

func NSApplicationMain(_ argc: Int32,
    _ argv: UnsafeMutablePointer<UnsafeMutablePointer<CChar>?>) -> Int32

And what does the second line of function help say?

"This method never returns a result code."

OK ;)
