Now that that works, one more question. Is it possible to hide the r that
is attached to every single type? For example to do something like this
(which doesn't compile):
No answer needed. Duh.. I can just pick r to be any type (like ()).
I've got intuitionistic logic and classic logic in
I've been struggling with this for the last day and a half. I'm
trying to get some exercise with the type system and with logic by
playing with the curry-howard correspondence. I got stuck on

Adding a couple of forall's makes it compile:

func1 :: (forall q . Or r p (Not r p) - Prop r q)
- Prop r (Or r p (Not r
