5883 - drop the `ref` keyword
When I created it I was conflating two things: a) needing to refer to just the start, rather than the whole, and b) counting indirections. Both are kinda ill-posed. Now Mu will have just `addr` and `handle` types. Normal types will translate implicitly to `addr` types, while `handle` will always require explicit handling.
