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, .... ?

PS: Yes, I realize this is a silly question but I'm borderline
obsessive compulsive about stuff like this. I can't help myself.
