I have personally no problems with calling a type "nullable" even in
Python, and, as a type *adjective* this seems to be the right choice
(i.e. I wouldn't say "noneable int" or "allow_none int"; the former is
no established or intuitive term, the latter is not an adjective).

As a type *flag*, flexibility in naming is greater. zeroes=True formally
creates a subtype (of string), and it doesn't hurt that it is not an
adjective. "allow_zeroes" might be more descriptive. bitwise=True
doesn't really create a subtype of int. For the feature in question,
I find both "allow_none" and "nullable" acceptable; "noneable" is not.
