[Pitch] - Variadic `print` function

[ensan-hcl (ensan)]

@Zollerboy1

func printTuple<each T>(_ t: repeat each T, separator: String = " ", terminator: String = "/n") {
    repeat print(each t, terminator: separator)
    print(terminator, terminator: "")
}

This implementation is a bit wrong. printTuple(42) will output 42<SPACE>, not 42.

I'm using this instead;

func print<First, each T>(_ firstValue: First, _ value: repeat each T, separator: String = " ", terminator: String = "\n") {
    func printWithPrefix<U>(value: U) {
        print(separator, terminator: "")
        print(value, terminator: "")
    }
    print(firstValue, terminator: "")
    repeat printWithPrefixSpace(value: each value)
    print(terminator, terminator: "")
}

Anyway, print(repeat each value) will eventually be supported. (Ref)
