Can't recall ever trying this.


The manual (https://docs.python.org/3/library/os.html#os.DirEntry) 
suggests that a DirEntry is one of those Python data-constructs which it 
creates, but we may only use: "cannot create".

Secondly, that a DirEntry object consists of a lot more than the 
directory-name, eg its path.

Thirdly, that os.scandir() deals (only) with concrete directories - 
unlike pathlib's ability to work with both the real thing and abstract 
files/dirs.


Why create a DirEntry? Why not go directly to os.mkdir() or whatever?
