[antlr-interest] Name Collision

I'm not sure if we can have attachments on this group, so I'm attaching and
inlining a .g file that recreates the problem. Note that even though some of
the content may not be relevant, it reflects what I'm using in my full
grammar. I just want to make sure you have all you need to recreate the
problem. You'll see the situation I described in the typeSpec() method.

Thanks,
Kevin
