 ghc is upwards compatible is living in a dream land)

 I'd be interested to know if the problematic changes were deliberate
 library changes, the new haskell98/base conflict, changes in the more
 experimental GHC extensions, or something else.

 > So it seems ghc 7.1 has recovered the loss incurred by ghc 7.0.

 Great, thanks for testing. I'll close the ticket then.
