[antlr-interest] I wish a dummy token is accepted by antlr

[Brannon King]

Can somebody post a link that contains the documentation on the # symbol? I
don't understand it (especially the way it is used in the code below) and
the documentation seems scarce and scattered throughout the newsgroup.

>>    dataType ID^ <AST=MiniJava.Identifier>
>>    { ## = #( #[...], ## ); }
>>    ;
