Hmmm? Everything in Python is an object.
Therefore! SURE. None *does* have attributes! ( even if not useful ones... )

eg: " None.__getattribute__( "__doc__" ) " doesn't produce an error.

In C, in Linux, at the end of the file "errno.h", where all error codes
are listed eg EIO, EAGAIN, EBUSY, E....) They had a final error like
the one you dreamed up, it was called "EIEIO"; and the comment read
something like, "All the way around Elmer's barn".



The poster just hit that strange wall -- *all* built in types are
injection proof; and that property is both good and bad...
