Attributes of None??!? :) > > ChrisA 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...
