Hare by Example: Tuples

Tuples are a bit of a mix between arrays and structs in they have a fixed number of elements, but they may have mixed field types and are referenced by index positions like arrays.

use fmt;

type point = (f32, f32);

export fn main() void = {
	// This is a nameless tuple of 3 fields
	let person = ("Blain", "Smith", 43);

	// Fields are access with dot-notation of their index.
	fmt::printf("{} {} {}\n", person.0, person.1, person.2)!;

	let p: point = (3.14, 8.98);

	fmt::printf("{} {}\n", p.0, p.1)!;

	// We can deconstruct the tuple into individual variables.
	let (x, y) = p;

	fmt::printf("{} {}\n", x, y)!;
};
