not) bytes.

method or attribute:



Almost - we'll put it in the os module

add to str:

No, not all strings are paths.

add to C API:

Yes.  Possible names include PyUnicode_FromFSPath and PyObject_Path -- 
again, the choice of bytes inclusion will affect the final choice of name.

add a Path ABC:


Sticking points:

Do we allow bytes to be returned from os.fspath()?  If yes, then do we 
allow bytes from __fspath__()?
