[Python-Dev] Got None. Maybe Some? (original) (raw)

Hey,

I'm a new lurker (hoping to change that) here on the python-dev list, and I thought I would post a message about a new PEP I recently submitted entitled "A Case for Some".

The PEP talks about how there exists None, that is false, and that is smaller than any other object ( min(None, a) -> None ). However, there doesn't exist an equivalent true value that is larger than any other number, like ( max(Some, a) -> Some ).

Personally, I think the introduction of Some offers a nice compliment to None, especially because it allows algorithms that require an initialization of infinity to not require large numbers. Some would be sufficient. It also has the side benefit of being funny.

I just wanted to get the discussion going. How does everyone feel about Some?

Thanks,
