[Haskell] Token Definition in Haskell

[Peter Theissen]

Hello,

i´m extending a functional language for some features.
(-> www.VeriFun.de)
Now i want to compare our lexing mechanism with
the Haskell lexer. Therefore i need a description
of the token definition regarding Haskell 98.
I already searched a lot but didnt find a short and
useful description of the grammar which is used
to parse Haskell expressions. Although a description
of the Parser would be nice.

I would be very glad if somebody could give me
further information and some references so that
i can mention them in my paper.

Cheers,
Peter
