Optional types number?, number??, optional declarations let x?: number, optional check if x? := foo()
As an aside, let x? with no type annotation is currently left alone during compilation.

I wonder what let x? should mean. I think most intuitively it would say "allow x to be unassigned on first access" but I'm not sure this is possible in TypeScript. Perhaps a helpful error message for now.

This started as an exercise to see which symbols we use the least (e.g.
~). But I think it could be helpful also as:#mean here?)I'm open to better ideas of where to put it, though. Also let me know if I missed some!
