Thanks! And sorry for late reply.
The answer for me means that I should use common method of separate lexem /
parser instead of using parsec with Char Parser.
I will do that anyway since it will probably improve the performance of the
parser.
One more question:
Do you know If there is a lexing technology which can inter work with Parsec
based Parser ?
With inter work I mean that line number information is preserved across
lexing/parsing.

Thank you very much, especially for the "cabal list ..." part :)
Have you got any experience with mentioned libraries? Would you
consider them "decent" (with all due respect to the authors)?

Yes, you can use Alex lexers with Parsec for instance. The pattern to
do this covered in section 2.11 "Advanced: Separate scanners" of the
Parsec manual. For a full scanner this unfortunately leads to quite a
bit of boilerplate so usually I use Parsec's own tokenizing code via
Token module.

Ive a related couple of questions:
Whats with the word 'Data'? Almost every Haskell module seems to be under
Data. I dont get exactly the usage of the word.
Also is there some easy way of browsing up and down the hackage hierarchical
structure?
[I know about hoogle and hayoo. I perhaps dont know how to use them well]

Haskell has so many pure functions and utilities, that nearly
everything falls into data manipulation if you think about it. IO
related things tend to be in system. Control has concurrency and
monadic stuff. Most larger applications have their own toplevel
module like Yesod, or XMonad. Mostly it comes down to, it feels
appropriate to put things in Data most of the time, especially if it s
a small library that does nothing on its own, so people do it.
When I want to browse a hierarchy, I go to ghci and type :bro Control.
and hit tab to complete on all the ones, then look at ones that
interest me. If I want more info, look up that import in hayoo and
read the haddock documentation for it.

Unfortunately, I don't have experience with any of them (I'm a beginner
myself).
The approach I usually take in this kind of situations is to read the source
code myself (is it "clean"?), get in contact with the author and the
community involved (is it actively maintained?) and test the library (does
it do what I need?)!
