I was reading about the following grammar on page 287 of the PDF document

grammar t;
s : X r A B
  | Y r B
  ;

r : A
  |
  ;

I don't see where the problem is since the alternatives in s begin with two 
different tokens X and Y.  I think that since these two tokens are different I 
can easily construct a DFA that would unambiguously parse a stream of tokens.

I sense that this example was supposed to bring out a finer point about how 
ANTLR generates parsers but I'm afraid that it is being lost on me.


Regards,
Alan
