Well, it's a matter of opinion.  The best implementation for some of us
(who are trying to develop portable software) would be one that detects
the nonportable usage (null pointer argument) and makes an appropriate
squawking sound, so we can fix our programs now rather than much later
when the bug causes mysterious behavior on another system.  Others would
say that the implementation should not waste any cycles testing for
things that it is not required to handle.  Still others would agree with
you that it would be nice for the implementation to accept this usage.
