Supprting static getter/setter

I've implemented a good majority of the getter/setter syntax for objects which was pretty easy due to the already implemented functionality of __get()/__set(). For static getters/setters there is no such obvious place to hook the new functionality, I was considering modifying the ZEND_ASSIGN opcode which would look back to the previous opcode (which should be a ZEND_FETCH_W) to identify the class/variable and then call the setter when appropriate. Does that seem like a good strategy or would you recommend some other way? -Clint
