Hi everyone,

I submitted a PR today, and Serhiy decided it needs a discussion on python-ideas and agreement from core developers before it could go forward.

BPO: https://bugs.python.org/issue40752 
PR: https://github.com/python/cpython/pull/20348

Today I wrote a script and did this:

    sorted(paths, key=lambda path: len(str(path)), reverse=True)

But it would have been nicer if I could do this:

    sorted(paths, key=len, reverse=True)

So I implemented `PurePath.__len__` as `str(len(path))`.

Serhiy and Remi objected, because it might not be obvious that the length of the path would be the length of string. 

What do you think? Can I get some +1s and -1s for this change?


Thanks,
Ram.
