Tuples

Tuples

A tuple is a collection of values of different types. Tuples are constructed using parentheses (), and each tuple itself is a value with type signature (T1, T2, ...), where T1, T2 are the types of its members. Functions can use tuples to return multiple values, as tuples can hold any number of values.

var ituples = (1, 2, 3, 4);

fun print_tuple(tuple (int64, int64)) {
    printf("%d\n", tuple.0);
    printf("%d\n", tuple.1);
}

struct Tuples {
    ituple (int64, int64);
    ftuple (float64, float64);
}

fun return_ituple(x int64, y int64) (int64, int64) {
    return (x, y);
}

fun make_tuple<T>(x T, y T) (T, T) {
    return (x, y);
}

var tuple = ([1, 2, 3], ["a", "b", "c"]);
for 0 .. 2 {
    printf("%d - %s\n", tuple.0[it], tuple.1[it]);
}
