David, Excelent point. It looks like a design decision is required here (i.e. portable aliases vs. proprietary pass-through). Personally, I like the idea of portable aliases for special features, as I'm not sure how I'm going to plug Hibernate's dialect information into the parser. It's probably

It does not pose much of a problem for the grammar, especially if the tokens are such that this can be done with the lexer. Then it is simply a matter of plugging in the pass through token into the grammar where it is appropriate (e.g. as an expression 'atom'). Don't know what it means for the ba
