While loops

[JacquelineCasey]

Requires #2 Booleans.

Once if statements are added, while loops should be pretty easy.

Should we add break and continue? How might those work in the future if we don't add them now. Can we break to an arbitrary outer loop? Outer block even (see Zig)?

[JacquelineCasey]

Do we want something weird like while-else or while-finally? Do we want a separate loop construct like in Rust?

I do think that for loops can wait until we get collections to loop over.

I think break statements and while-else can be postponed for now. There's a chance we will have better machinery for breaks / continues after we do #14 and especially #5.

I like the idea of Zig's continue clause...

Basic while loops done!
