Comment (by [EMAIL PROTECTED]):
Just for the record, it isn't just type signatures in patterns:
{{{
[EMAIL PROTECTED] stuff]$ cat R.hs
$(id [d| f :: forall a . a -> a
f x = (x :: a) |])
[EMAIL PROTECTED] stuff]$ ghc -fglasgow-exts -c R.hs
ghc-6.4.2: panic! (the `impossible' happened, GHC version 6.4.2):
Failed binder lookup: a{tv a189}
}}}
