I've counted 63 cases of ``map(None, ...`` in my company's code base.
You're probably right that most of them could/should use zip() instead;
I see at least a few cases of
map(None, field_names, values)
but it's not clear what the expectation is for the size of the two lists.
(None of the uses were created by me -- I abhor map(). ;-)
