Object LazyInvoker::invoke	(	const Reflex::Object &	o,
		std::vector< Reflex::Object > &	v
	)		const

invoke method, returns object that points to result (after stripping '*' and '&') the object is still owned by the LazyInvoker the actual Reflex::Object where the result is stored will be pushed in vector so that, if needed, its destructor can be called
