Sorry. The previous email was sent before I finish it.

Hello all

I am developing an Objective-C 2.0 grammar using the Antlr v2.7.
The problem I'm facing is that there exist some ambiguous reserved words.
For instance and using k = 1 in Lexer, there exist

@protected, @private, @public, @interface, in, inout, ...

defining these regular expressions like:

AT_PROTECTED : "@protected" ;
AT_PRIVATE : "@private" ;

Using this approach, of course, I get a lot of warnings because they are

How do you suggest to solve them?

Factorize them and then set the token type accordingly?
