The existing parser is pretty hard to understand and extend.
We're probably a few man-months away from the point of
diminishing returns, and I'm sure there are some bugs
that can't be fixed without a rewrite.
Have you read it enough to understand it yet?

Incremental improvements to the current parser would still
be welcome and useful.  For instance, supporting cmd /a
( see http://bugs.winehq.org/show_bug.cgi?id=21174 for
someone's draft patch ).
