Prohibiting `get_class(NULL)` is certainly a good idea, but I have some concerns regarding BC. While `__CLASS__` has been introduced with PHP 4.3.0, it had the glitch to return the lower-cased class name before PHP 5.0.0. So there *might* still be PHP 5 code around using `get_class(NULL)`. The deprecation might be more appropriate, and could equally well catch an inadvertent `get_class(NULL)`. -- Christoph M.
