Dear Fellow Bug Chasers,
ghc-2.05 (with some patches applied ;-)) does not digest the following
program:
module Test ( module Test )
where
import List
class Sequence s where
fromList :: [a] - s a
toList:: s a - [a]
instance Sequence [] where
To partially answer my own question...
Big problems with some output from Happy 1.2-alpha [...] I'm quite keen
to get it sorted out and/or worked around.
Easiest work-around is not to use "happy -g" output, which I neglected
to mention I was using. Evidently some sort of type-checking
