Interface for __get, __set, __isset, __unset?

Is there an interface for: interface ??? { public function __get($name); public function __set($name, $value); public function __isset($name); public function __unset($name); } I have a bunch of classes that use this and I'm trying to normalize things. I'm been trying to think of a good name for it but I'm stumped. What would you call this interface? Container, ObjArray, DyObject, .... ? Mike PS: Yes, I realize this is a silly question but I'm borderline obsessive compulsive about stuff like this. I can't help myself.
