[antlr-interest] lexical filters in v4?

It doesn't seem like v4 supports lexical filters?
Using the example here: http://www.antlr.org/wiki/display/ANTLR3/Lexical+filters
The generated code is:
System.out.println("found var
"+(_localctx.name!=null?_localctx.name.getText():null));
Which caused the Java error:
"name cannot be resolved or is not a field"
I need to be able to match a closing tag against an opening tag (which
may have assorted nested tags), which means I need some way to extract
a tagname during the opening rule, and check against it in the closing
rule.
Any recommendations for how to handle that?
