[antlr-interest] minor issue with comments...

Ok, this may be the most minor issue alive today, but if you put comments on
multiline code statements antlr doesn't like it. As in:

local_variable_declaration!
 :  tp:   type
    lvd: local_variable_declarators

    { #local_variable_declaration =
       #(   ([VariableDeclStmt]),
             ([TypeRef], tp),
             ([ModifierAttributes]), // comments not allowed here
              lvd
        );
    }
 ;

I can understand why it is like that looking at the gen'd code, just it is
sometimes useful to have a comment there - in this case to explain why a
node is created for no seemingly good reason. Maybe there is some form of
'grammar only' comments I'm missing?

Anyway, not a buring issue obviously, just thought I'd mention it in case it
hasn't been noticed...

Cheers,
Robin
