I would think the solution to this is pretty straightforward. Basically, a Quasi is not a single token. the grammar in the proposal can almost be read that way right now. It should only take a little cleanup to factor it into a pure lexical part and a syntactic part. A few [no whitespace here] tokens will probably be needed Allen _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
