[antlr-interest] Unreachable production

[andrei.majidian at bt.com]

Hi

I am trying the Interpreter for the following grammar Name.g

_____________________________________________
grammar Name;

start: wordList ;

wordList: '[' Name (',' Name)* ']';

Name:	ID | QW;

ID:    ('a'..'z'|'A'..'Z')+ ;
QW:    '"' ('a'..'z'|'A'..'Z') (' '|'a'..'z'|'A'..'Z')*
('a'..'z'|'A'..'Z') '"';
WS:    (' '|'\t' |'\r'|'\n')+ {skip();} ;
____________________________________________________

With the following input:

["wild  animal", "friendly", timid]

It gave me the following Warning in the console

"[21:52:57] warning(208): Name.g:10:1: The following token definitions
are unreachable: ID,QW
[21:52:57] Interpreting..."

What does this mean?  The parse-tree is correctly produced. I don't
understand the warning.

Thanks

Andrei
