Is None so weird? All I am proposing is a symmetric value to None.
To me that would be All of AllType. Some is in between. Can you think of any uses for All other than being max element?

Not really. However, I was thinking of Some in the context of graph and dynamic programming algorithms. When programming some algorithms in Python, you need to either pick some large constant (that you hope will be big enough), or have a test to see if a value is None. That is ugly and very not Pythonic. I do like All and AllType though, which gives a better name, as suggested by Guido. - Josiah
