We could make this more consistent in two ways. Alternative (A): One way would be to make it clearer that $wMkT was the real constructor:
data T = $wMkT Int Int MkT p = case p of (x,y) -> $wMkT x y f x y = $wMkT x y g t = case t of $wMkT x y -> x
Alternative (B): The other alternative would be to make the original Haskell constructors into the $w things:
data T = MkT Int Int $wMkT p = case p of (x,y) -> MkT x y f x y = MkT x y g t = case t of MkT x y -> x
As someone using external core, I can resoundly say: I don't really care :). I would probably prefer (B), as you seem to, but it's not a strong preference.
