[antlr-interest] Variables starting with _

[Andrew Deren]

It seems antlr won't accept variables that start with _ (underscore)
for example, a parser rule:

rule { Exp _exp = null; }
    :
    _exp = exp
    ;

will result in TokenStreamException. I don't know if that is meant to be
that way, but I would think it should be fine, because _exp is valid
java/c++/c# variable name.
