I have a use case for this in Serde, so would be in favor.
We should not block this kind of improvement on the hope of generics. Worst case, we have this plus
generics so you have options, how terrible.
Rust-style associated types would probably work as well. I'd be fine with that approach, too.
One could argue they're more valuable as a sort of "junior generics," but absent
anyone able and willing to implement them, again, worst-case we end up with options in the future.
