It's probably not a bug that it choked on it, but it might be a 
bug that it didn't *detect* that it was choking on it and give you 
an error message instead... :)

But error detection in general in ANTLR is fairly rudimentary at 
the moment.  Hopefully that'll get better once ANTLR v3 is 
self-hosted.  (Which'll be in 3.3, isn't it?)
