[Python-ideas] [Python-Dev] nodef

[Terry Jones]

Adding nodef would be another step on the road to anarchy and nihilism. It
wouldn't be long before people began using nodef as a possible value for a
function, and then where would we be?

Besides, using xxx = object() seems like a safer bet. Your code is unlikely
to be accidentally called by someone else using your semi-private xxx
object. If there were a documented official nodef object, someone would
eventually call you with nodef instead of None.
