Description
it would be nice to be able to do the same kind of `+T` `+?` `-T` `-?` type edits with `@as` that we can do with `@cast`. Primarily for removing a maybe-nil from a return value in cases where the programmer knows it won't really be nil.

Research direction
Start by comparing how @cast handles +T, +?, -T, and -? type edits with the existing @as annotation behavior. Done means @as supports the same edits, including removing a maybe-nil marker when the programmer knows the return value is non-nil.
