To be honest, that’s exactly what we might want to avoid. Last time someone wanted to do actual improvements to our lexing they were stopped because changing tokens would mean breaking code that relies on `token_get_all()` which is a core extension user land function. It might be though that it’s only the problem with lexing and it should not be a problem for AST because it is, ahem, abstract. -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
