I second this advice: Our research group uses the ouput of PCCTS in
countless ways in C++ programs, and Ter Parr (who wrote a big chunk of
PCCTS) provided phenominally quick modifications whenever we ran into a
glitch. He didn't stop until it was _right_.

BTW the archive for PCCTS has changed; its new location is at ( in the directory /pub/pccts. Try
it, you'll like it.

Ter and I have talked quite a bit about this. His ultimate goal is to
write a parser generator in an object oriented language. The current
problem with C++ is that there exists no compiler for it which doesn't
have prohibitive bugs in it. He has tried repeatedly for several years
now, but now appears to be quite disgusted with C++. He is investigating
writing his own bug-free OO language in which to do further developement
