Custom object storage

Is there any way to storage (and access) custom variable with my class? For example I need to access the same zendobjectiterator from many places inside my class with %{ closure. Example:

%{

zendobjectiterator *iterator;

zendclassentry *ce;

ce = ZOBJCEP(result);

this->iterator = ce->getiterator(ce, result, 0 TSRMLSCC);

}%

I read about custom object storage here: http://www.phpinternalsbook.com/classes%5objects/custom%5object%5storage.html but i don't have any idea how to implement same solution beside zephir.

This is not implemented in Zephir currently
