I certainly will not claim to be the arbitrator of good and bad practices

This is a little off-topic, but I'm curious, since usually, for public
functions and classes, I do
__all__ = (Class.__name__,
Why not just __exclude__ or __excluding__?

That is true, but that is also Python. If you import something not included in
`__all__` then you do so at your own risk as it could change or vanish in

Absolutely!

That is its purpose. :-)
I do think something like __exclude_all__ would be handy. It can be annoying
to have

Sort of. That will only work if you define __all__ at the end of the
file. But usually you want to define it at the beginning as a sort
Hi Ethan,
I'm sorry, I take that back, that convention was codified in PEP8.

Hi Ethan,
I'm not convinced that __all__ is responsible for codifying the api. The
contents of __all__, does not stop anyone from importing anything in the
module using `from foo import bar`. __all__ is specified in the tutorial as
being included for the `from foo import *` case:

You could implement that yourself:

The primary purpose these days for `__all__` is to codify a module's API. The
