Ah, yes.  I'm not a language lawyer, but I believe the current C++
standard says that new _must_ throw an exception on failure, not return
null.  (At least by default, I think there is a 'nothrow' option.)  I
believe VS didn't/doesn't honour the standard here.

Another thing many people don't know is that it's perfectly ok to pass
null to delete.  So there is never a need to write:

if (anObject)
  delete anObject;
