Folks, Whether it's $$ or !# or $0 or any other random symbol doesn't really matter. What matters is the introduction of a new symbol for this purpose and the non intuitive nature it will have. This is not analogous to the namespace operator, where it was obvious we wanted namespaces, and was only a matter of picking the right one. It's also not analogous in the sense that codebases that use namespaces tend to use them all over, so the likelihood of not being acquainted with it is slim. Here we have a completely optional syntactic sugar, that's not nearly as widely useful as OOP or namespaces, and the question is whether the added complexity of a new operator, a new symbol and the new semantics around them both are worth the benefit of introducing them. IMHO it's not. Zeev -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
