I'm working on adding a numeric_owner parameter to some tarfile methods
(http://bugs.python.org/issue23193),
In a review, Berker suggested making the parameter keyword-only. I agree
that you'd likely never want to pass just "True", but that
"numeric_owner=True" would be a better usage.
Boolean parameters are the classic problem that keyword-only parameters
solve. It forces the caller to provide context for the parameter,
solving the mystery-meat API problem of
tarfile.extractall(".", None, True)

But newer parts of stdlib, e.g. asyncio, visibly overuse kw-only args.
Overuse? asyncio? You mean "that thing Guido just wrote last year"?
The most practical definition I've heard for the word "pythonic" is
"code like Guido writes".
