Comment:
seems tricky. I hope it can be done in a way that makes the language feel
no more complicated. e.g.
{{{
type F = !Int -> Foo
data Foo where C :: F
}}}
seems fine and similar to something I've wanted to do (but didn't try)
(when there were multiple similar signatures in my GADT). The explicit
signature on a thing (of course, explicit signatures are required for data
declarations) is what can coerce it to be strict, I guess.
