yup -- and it there were a lot of commonly used APIs that took strings, and
multiple timedelta implementations, then it would make sense to introduce a
I don't think the use-cases rise to that level, myself. Though if someone
wanted to put a call in to obj.totalseconds() into time.sleep, that might
actually be worth it :-)
(now that yo mention it -- I have a substantial library that uses seconds
internally, and currently has an ugly sometimes integer seconds, sometimes
timedelta API -- maybe I'll introduce that protocol. Not sure why I didn't
think of that before now.
Because I'm passing it to modfoo.dosomethingwithafile() which takes a

It can't -- modfoo could be a third-party module -- it is impossible for
Path to grow everything that any third party module might support.
