No, I did not. In fact I didn't know about this project, but it looks
very interesting. I'll definitely go and look at the code.

One of the reasons I started worked on a MediaWikiParser was because I
wanted to use the Haskell language and some of its tools rather than just
read about them. I'm not really interested in making a clone of something
that already exists just for the sake of ideology (although personally
I'm much more fond of BSD-style licenses than of GPL).

On a side note: are there any lexer/parser generators out there I should
be aware of? As mentioned in my original post I've tried using Happy, but
I was unable to understand its very concise error message 'parE'.
It would be really nice to have a tool that generates an AST automatically
(e.g. something like ANTLR).
