The context would make it clear which kind of cast is required, but you could only do a single one of the casts at once (so, only const_cast or static_cast, but not both at the same time). The rules for this cast would be a little stricter than C-style casts. I could certainly get behind this. But I'm totally against C-style casts (but, feel free to use them yourself).

`as` proposal was interesting (+ match syntax). It could fix a couple
things at once.
I wonder what the status is now of it? Do Herb plan to continue it?
