Yes, correct. > My personal opinion is that we should be working to eliminate > differences between internal and user functions (including closures). > In your opinion can we make user and internal closures act more alike? > I'm assuming rebind internal methods can't be done properly because > internal objects may use different C structs than a plain zend_object > (hence the crashes). Is that correct? It's rather about the additional meta-data before the object which the internal object requires. Hence you usually can use internal objects like normal zend_object *'s, but not the inverse. The only way to make them actually more alike is putting more restrictions (and BC breaks) than necessary onto the binding rules. Loosening internal binding rules doesn't work as well...
