We already have CastToString, it's __toString. I'm not sure we need a named interface for that, as checking for the method would be basically the same, and practically I do not see anybody wanting to type against such type (i.e. you'd do foo(int $a) but not foo(CastToInt $a)). As for others, we in fact have cast_object handler for the objects, so extensions can already do that. Giving user functions access to it would be not hard, though I'm not sure it won't complicate some things. But I think if enough people need it, enabling full user-space access to cast_object should not be a problem. Definitely needs a good RFC though with good convincing examples of use cases. -- Stas Malyshev smalys...@gmail.com -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
