[Python-ideas] New PEP proposal -- Pathlib Module Should Contain All File Operations

[George Fischhof]

Hi Folks,

it seems for me that the welcoming of this proposal is rather positive than
not.

Of course several details could be put into it, but I think it would better
to let the developers decide the details, because they know the environment
and the possibilities.

The name of the functions and the method they solve the problem (for
example rmdir(tree=True9 instead of removedirs()) is all the same.

The (main) goal would be that file and directory operations reside in one
module. And currently the pathlib seems to be the best candidate.
(we could put then into a very new module, but it would be just another
duplicataion)


So what do You think, this proposal IS PEPable or should I do something
with this to achieve the PEPable state?


BR,
George
