Summary: panic:Unify.unifyTauTyLists
Initial Comment:
The attached sample program triggers a panic because I forgot to
pass the type argument in the recursive algebraic datatype
construction. The commented line is correct.
GHC should not panic but instead provide a helpful error message.
(Unluckily, I won't be able to test this with -HEAD atm)
Compiling Main ( bugs.hs, interpreted )
ghc-6.4: panic! (the `impossible' happened, GHC version 6.4):
Unify.unifyTauTyLists: mismatched type lists!
