That's correct behaviour.  Now if you had written { $text = ""; } 
and it was still outputting 'text = "";' then you might have had 
an argument... ;)

Because that's what you wrote.  Unless you use the $ prefix (which 
you're supposed to use whenever you refer to any ANTLR-provided 
parameters, fields, etc) then ANTLR will leave your code 
alone.  It assumes you know what you're doing.
