Chris,


Thanks a lot ... I've hacked my way round a few of these, but never
really summoned up the courage to do a clean job of it. I ... acting
like the nervous beginner to compiler compilers that I was at the time,
settled for : "Least possible source code change, lest I break it"!

Yes. My later scrutinies suggest that plenty could be done to make both
the programs and their output source far more amenable to OO.


In particular, I'd love a parser framework which elegantly does garbage
collection on all the objects in the parse tree. I have one, but it's
not exactly wonderful.


MH.
