Give an error.

No, a hybrid wouldn't be very useful.

Ummm...sorry for the newbie question. How do I get ANTLR to produce a 
parse tree?
I looked through all instances of "parse tree" in the book and couldn't 
find the answer. I
see that ANTLRWorks shows it, and obviously the code itself is a parse 
tree. But is there
some option that says "give me the parse tree as a data structure?"
