Haskell Parser in Hugs

[Martin Erwig]

I am wondering what is the best way (in terms of
easy-to-use and easy-to-install) to use a parser
for Haskell in Hugs. As far as I know the parsers
by Sven Panne and Manuel Chakravarty require ghc.

In any case, wouldn't it be a good idea to include
with each Haskell implementation a module "AST"
that defines a representation of Haskell programs
and offers functions like "parse" and "print"?
