[antlr-interest] Bug using scopes, rule parameters, java code gen

[Joseph Gentle]

If I have a simple parser:


grammar test;

foo
scope
{
	Object x;
}
: bar;

bar	:	confabulate[$foo::x.toString()];

confabulate[String y]:'y';


... when it actually calls confabulate there it generates this  
incorrect code:

             confabulate(((foo_scope)foo_stack.peek()).x, .toString());

instead of:
             confabulate(((foo_scope)foo_stack.peek()).x.toString());

The problem has something to do with the '.' in the parameter list  
being parsed incorrectly.

There's a work-around using temporary variables, but its ugly.
