generators & php tools

Hi! I was looking into generators topic and I couldn't find answer to this question: how generators are supposed to interact with PHP tools, such as debuggers, profilers, etc.? Specifically, how calls to generator are handled? Usually, the tool overrides zend_execute and zend_execute_internal and every function call goes through there. But generator does not use these - it uses execute_ex instead. So can generator be debugged/profiled? What happens if I say "step out" inside generator - would that work? -- Stanislav Malyshev, Software Architect SugarCRM: http://www.sugarcrm.com/ (408)454-6900 ext. 227
