[antlr-interest] Updated ECMAScript 3 grammar

[Patrick Hulsmeijer]

Excellent idea. I've played with parameters in the expression rules in
the past to actually accomplish the same as you did. But this was not
successful.

After reading your post I thought I give it a shot with global scopes.
But this gives me the same result: an enormous DFA generated in the
parser and a failing prediction. I will try to look into this more
closely and report this later.

Gr, patrick.

For a similar grammar[1], I did the In/NoIn stuff using scopes rather
than duplicate rules.

I wonder if you found particular reasons not to do things that way?
Maybe the performance is better?  (Maybe I've actually implemented my
grammar incorrectly?)
