I've done some final updates to the RFC ( https://wiki.php.net/rfc/token_as_object) and intend to open voting tomorrow, if there are major objections. The last changes were to clarify that getTokenName() returns null for unknown token IDs, and to provide some more extended rationale for what the individual methods are useful for. @Michal: The reason why it's called PhpToken is that it is ... a PHP token :) At least that's what it is intended to be used for -- while you could technically use it to represent other kinds of tokens, I don't think that's a usage that should be endorsed. Just "Token" is very generic, and not even specific to lexing/tokenization. The term "Token" is commonly used in other contexts as well (e.g. token ring). Regards, Nikita
