[antlr-interest] Reporting bugs

[Jim Idle]

These are already reported. There is a finite amount of time to fix 
things unfortunately and your comments are noted and they are correct, 
but until the ANTLR parser is written in ANTLR3 it is difficult to catch 
some of these things and that hasn't risen to the top of the list yet I 
am afraid. So, in the short term you have to get experience. Though it 
isn't quite kosher to say this, it does actually help you to understand 
what is going on ;-)
