Hi, some background about my pathlib usage. I use the backported version of pathlib and tried to replace the usage of path.py (also widely used library).
Some features part of path.py missing in pathlib: - expanduser, expandvars, I have to use the os functions to do this. It is possible but better if this is part of pathlib. - shutil stuff, as noted below - dirs, and files from path.py. I often had to traverse a directory. I know this is possible with a generator. But It is so often needed that I missed this. Simple dirs(pattern) and files(pattern) is enough. With support for "**" as recursion. Pathlib is a great library and it was good to add it to the standard lib. Now it is time to improve it further.

Even if the state is global. But has to be noted in documentation. > # > 3 > .

Also, this would be required for the TmpDir path). I also often needed this. Thanks for bringing this up.
