It might be easier to extend nhc98 with some of the extensions needed by
ghc. Actually, how difficult would it be to translate ghc core to
something nhc could use? Then we could use the ghc front end with nhcs
back end. I am not sure what nhcs intermediate language looks like, but
ghc core is similar enough to desugared haskell that it seems like it
should be possible. The main issue I can think of is a mismatch in the
primitive operators, so one would probably have to use ghcs front end
with nhcs prelude/other libraries.
