RE: GHC hang
There is definitely a performance bug somewhere in GHC, and we're collecting cases that show it up. It'd be ideal if you, or someone else, could snip out a standalone module or two that demonstrates the problem, rather than all of WASH. If not, we'll try to tackle it directly.

I've got a happy grammar that takes ghc many minutes and hundreds of Mb to typecheck if I leave off the types for all the productions. If I add types for all the productions it's pretty quick and uses very little memory. But I think this is a known issue (it's mentioned in the happy manual) and not the one you were interested in. Am I right? I was just suprised that it is such a dramatic effect!

However, I sent a cc to the wrong mailing list :-). But indeed it takes a long lng time, but it compiles.
