I agree - ANTLR seems to work pretty well (correctness), but what we need
now is SPEED!
We've got ANTLR in a couple of our products, but they parse mainly small
files. Sometimes, however, we will have to parse large files, and I think
we'll have some customer complaints from that.
So, the slowness is a big issue here as well.
We can also offer to contribute to the C++ code generator work, if that
helps. Especially if some smaller pieces can be broken off and worked on
separately.
