__autocreate() function for non-existing variables

Hello. I think that it would be useful to allow an __autocreate() function create non-existing variables just like __autoload is called for non-existing classes. The function will be called when an attempt is made to read a non-existent variable. It will return a reference to the new variable it creates. This could be very useful in some cases. For example it could be used in a php library that creates a database object. When some function tries to use the database object, the __autocreate function will check if a global database object exists. If it does not exist the function will create the database object as global and in either case return a reference to the object. I am willing to implement this functionality, but I'd like to hear the opinion of the PHP developers first and especially of the Zend2 team because this functionality will modify the Zend2 engine. vesselin
