tuples.swift

// The sad state of tuples in swift 4

func test() {
    return () // why is it not mandatory ?
}
// func test() -> Void {} // error: invalid redeclaration of 'test()' why is it a redefinition ?

/*
 The problem is that Void in swift is not the "Absence" of a parameter but the type of the empty tuple
 We should change the definition to:
 */
typealias Unit = ()
let unit: Unit = ()

// Void should not be considered as empty tuple but should be an intrinsic and always be flattened
