[antlr-interest] Restarting a rule

[David Penton]

Sorry to answer my own post, but I see that my first question in the
original post does not require an answer.  I am barking up the wrong
tree with that approach; I think I need to be doing token filtering
instead.

I would appreciate confirmation that there is no way to set global error
code in a parser (i.e. exception handling code for every rule.)
