On a more specific note, its the 1st line:
class filter(object)
which knocks me off.
If a more restricted type from the ABC was shown which exactly captures all
the iterator-specific stuff like __iter__, __next__ it would sure help (me)
Since it's not actually derived from anything else, I'd leave that part
alone. But it could be useful to add something like:
ducktype: collections.abc.Iterable
if nothing else, it'd get beginners to the language to start thinking
more of what duck typing is, in Python.
