Sloppy parameter handling of some reflection methods

Hi, while working on the arginfo stubs for ext/reflection, I've noticed that several methods do very sloppy parameter handling, if called for static properties/methods. ReflectionMethod::getClosure(), ReflectionProperty::getValue() and ::isInitialized() don't do any parameter checks at all, while ReflectionProperty::setValue() accepts arbitrary zvals as first parameter, and simply ignores the argument. If we wanted to be extra strict, we could do zpp_none() checks for the first three methods, and only accept a $value argument for the fourth. For BC reasons as well as simplifying code which deals with non-static properties/methods as well, we could also support an optional NULL, and maybe even an (arbitrary) object of the respective type. Thoughts? Thanks, Christoph
