[antlr-interest] bad generated code?

Good suggestion, but unfortunately the code generated for name is
still the same. I don't understand antlr could ever generate code
that looks like:
if ((_t.getType()==A) && (_t.getType()==B)) {}
When A is not the same as B. I'm guessing, however, that a treeparser
generator is more complicated to write and probably not as often
used/tested by antlr users as a normal parser generator (most people
I've talked to here at UC Davis only use it for parsers and lexers,
not AST traversals).
Any other ideas? I appreciate your taking a look at it.
