Examples

Simple program:

subscript longer_of(_ a: inout String, _ b: inout String): String {
  if b.count() > a.count() { yield &b } else { yield &a }
}

fun emphasize(_ z: inout String, strength: Int = 1) {
  z.append(repeat_element("!", count: strength)))
}

public fun main() {
  var (x, y) = ("Hi", "World")
  emphasize(&longer_of[&x, &y])
  print("${x} ${y}") // "Hi World!"
}
