Destructuring arrays and objects.

[StarArawn]

It would be nice if we had syntax to destructure arrays, objects and other types.

Syntax could look something like this:

let my_array = [0, 1, 2];
let [a, b, c] = my_array;

print(a); // 0
print(b); // 1
print(c); // 2

This is similar to JavaScript and this also lets you emulate tuples! Like:

let my_tuple = ["Hello", "World!"];
let [hello, world] = my_tuple;
print(hello); // Hello
print(world); // World!

This might be doable as Rhai only contains two literal syntax that can be matched against: arrays and maps. I'll look into that.

But then, once we match on arrays, we probably need the spread operator ... to do whacky things like match both ends, match the middle etc.

So it must consider all possible combinations: [a, b, c], [a, b, ...], [..., b, c], [a, ... c], [..., b, ...]...

And if you add _ to match one slot, then there will be many more patterns to handle.
