Dearest GHC hackers,
We're considering the possibility of organising a GHC Hackathon around
ICFP this year. This wiki page has tentative details, and you can
indicate whether you'd be interested in coming, and give us your
suggestions:

Hello,
I am wondering if the following patch (or equivalent) made it into
GHC 6.4.2. I was hoping it would fix my problem:
mjollnir ~/src/ghc/ghc-6.4.2$ ghci `hbdd-config --cudd-libs`

This code compiles properly (with -fglasgow-exts on GHC 6.4.1):
class CC a
type C x = CC a => a x
f, g :: C a -> Int
f _ = 3
g x = f x
But, this code:
class CC a
type C x = CC a => a x
f, g :: C a -> Int
f _ = 3
g x = f $ x -- the only change
gives this error:
Inferred type is less polym

delete the "not allowed" comment ;-)
It's not so simple as I'd thought so I'd be interested to know the reason
for $ making a difference too.
Regards, Brian.

The problem is exactly the use of $. $ is an operator, not a built-in
language construct, and it has type (a -> b) ->
