Description
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!

Research direction
The issue provides example syntax for array and tuple-like destructuring but names no files, tests, or entry points. First clarify the supported destructuring targets and semantics for arrays, objects, and other types. Done means the syntax and behavior are agreed and covered by tests.
