[antlr-interest] Lexer Inheritance

[robbugh]

Is there a way, in ANTLR 2.7.2, to sub type a lexer adding only a new 
token to the "tokens {}" statement, i.e., without adding new rules? 
Something like the example shown below: 

class mySubLexer extends myLexer
tokens {
   NEW_TOKEN = "new_token";
}
ANTLR reports an error in this case: 

unexpected token: null
