It seams like the CompuledParser have been broken for the last 16 years,
and that seams unbelievable.
The error I get is that "symbol" can't be found, and even I "fix" that the
parser always succeed, but with no children....
Is there a working copy of this file somewhere else that people use instead?
It seams like it's multiple merges that have gone wrong and that is what
have lead to this, I don't use hg so I can't help fix that. Anyone else who
would like to give it a try?
