In general, being able to specialise polymorphic structures so they look like unpacked monomorphic ones would be awesome.

(!Int, !Bool) -> (,) {-# UNPACK #-}!Int {-# UNPACK #-}!Bool

I repeat my concern about this notation and the implications thereof. (!Int, !Bool) cannot be passed to a function accepting (a,b). However, I feel there's something very useful here that should be fleshed out rather than hacked. For example, a theory of composable strict structures in a lazy language. Luke
