Copying is a little faster:

$ ./python -m timeit -s "from pathlib import Path" "Path('Doc').copy('Doc2', dirs_exist_ok=True, preserve_metadata=True)"5 loops, best of 5: 70.7 msec per loop  # before5 loops, best of 5: 68.7 msec per loop  # after

I played around with that idea, and I haven't completely ruled it out, but it's a bit of a rabbit hole.

On naming and re-usingDirEntry: I don't thinkos.DirEntry.from_path() makes sense. The purpose ofDirEntry is that it stores information from callingos.scandir() on theparent directory. I think we'd need a new class withname,is_dir() andis_symlink() attributes. We'd lazily generate an instance of this class fromPath.last_status (or.status, or soemthing), assuming there's not already aDirEntry stored. The new class could be calledpathlib.PathStatus or something along those lines.

Then we need to define whenos.stat() is called and when exceptions are raised. ADirEntry object is initially populated withsome information from theos.scandir() call, so we might want ourPathStatus object to perform astat() on creation. But should itos.stat() oros.lstat()? And doesn't that imply that ourPath attribute should be a method rather than a property, given itmay perform serious work? MaybePath.cached_status()?

Then we need to figure out how this interacts with the rest of thePath methods. ShouldPath.stat() andPath.lstat() automatically update the status object? Should it replace an existingDirEntry object with aPathStatus object? ShouldPath.is_dir() callself.stat(); return self.cached_status().is_dir()?

None of this is insurmountable, mind :)

Perhaps I'm overthinking this, and all we really need is aPath.scandir() method

Once you've decided on whether to continue on this work or not, please ping me again (sorry, I missed this one)
