Tuples

A tuple groups a fixed number of values, possibly of different types. Select a slot with .0, .1, and so on, or destructure the whole value in a pattern.

Tuples are value types, so binding or passing one copies its slots. A one-element tuple needs a trailing comma: (value,).

fn main() {
  let position = ("west", 3)
  let (direction, steps) = position
  println(direction)
  println(steps)
}
