Add an AS Equivalent to Option in Rust to the AS Standard Library #1410
Description
One thing about AS is that basic types cannot be nullable. However, I've been designing some APIs that need some nullable Basic types, and I've been working around them. But I think it'd be cool just to write up a quick equivalent to C#'s Nullable or Rust's Option.
I could super easily add this myself. I personally like C#'s interface more, but I think it should be named Optional. That way, it doesn't conflict with our already exisiting idea of nullability in the docs.
What do y'all think @dcodeIO @MaxGraey @jtenner @sirwillem ? 😄

I believe that this feature requires multi-value returns, if I am not mistaken.

It's just temporary limitation. And as @jtenner mentioned it's depending on multi-value proposal

Here was what I made a year ago when I was working with WASI and wanted to get the result and the error:

As @jtenner points out multi-value means that we don't have to deal with an allocation each time, but that might be okay for now.

Ahhhh that makes sense. I'll wait for that than, thanks everyone! 😄 👍
