Tuples

Tuples are fixed-size, heterogeneous collections accessed by index. They support destructuring in match expressions.

use system.io

let t = (10, "hello", true)
println(f"{t[0]}")   // 10
println(f"{t[1]}")   // hello

let pair = (3, 7)
let sum = match pair
    (a, b): a + b
println(f"sum: {sum}")
