[antlr-interest] lexical nondeterminism question.

syntactic predicates don't work across tokens ... so you'll
have to merge the lexer rules.

My suggestion would be something like this:

        : (NUM_INT_lookahead)=> NUM_INT
        | AMPERSAND 

    private NUM_INT : ..... ;
    private NUM_INT_lookahead: .... ;
    private AMPERSAND: ..... ;

Hope that helps a bit, Silvain
