Issue created Apr 14, 2004 by nobody@trac-nobody

double arrows causes a panic

Trying to load code like the following:

test = proc inp -> show -< id -< inp

will cause both ghc and ghci to panic with this message:

ghc-6.2: panic! (the `impossible' happened, GHC version
6.2):
        tcMonoExpr GHCziBase.id {- v r8k -} -< inp {- v
aPp -}

As far as I can tell, it's the "a -< b -< c" that's
causing problems.
