ghci 6.4 panic on HList code.

[Simon Peyton-Jones]

Yes, this is indeed a bug, happily long fixed.  6.6 says

Foo9.hs:1:34:
    Class `C' used as a type
    In the class declaration for `C'

| sorry, i was too fast with my report.  i still consider what i found a
| bug in ghci, but it's triggered by a bug in my code.  you can also
| trigger it by the much shorter:
| 
| module Main where class C a where f :: C a
| 
| in contrast, the more correct:
| 
| module Main where class C a where f :: a
| 
| works.  feel free to fix it anyhow, of course...  (-:
