I believe the preferable solution is typeclasses as record types, instances as records, scoped implicit parameters for propagating them around, associated types as record members, and a backtracking logic solver for instantiation. But that just solves the immediate problem; on top of that I'd like a dependent type system with staging to enable type dependency on values (e.g. arrays-with-length), and a higher-order logic solver so simple logic-programming idioms like let zip(as,bs)=f(x) in ... can be expressed and translated via instantiation into efficient runtime code. And a total (non-partial) function subset of the language for reasoning with proofs as programs. — Tim Sweeney
