I have a few questions 1. Apart from wrapping zend_resource into ResourceContext, has there been discussions or ideas to wrap other things ? 2. Are there any scenarios where using with() is a bad idea or has "side effects"? 3. In the implementation code there is a lot of mention of "list" and zend_list .. why? Maybe the answer is obvious but I can't see, at first glance, why we are implementing list under the hood. Thanks, and great work to both of you! > -- > Larry Garfield > larry@garfieldtech.com >
