Kevin Norris added the comment:
If I were designing pathlib from scratch, I would not have a separate Path
class. I would instead do something like this:
In pathlib.py:
if os.name == 'nt':
Path = WindowsPath
else:
Path = PosixPath
Alternatively, Path() could be a factory function that picks one of those
classes at runtime.
Of course, that still leaves the issue of where to put the method
implementations which currently live in Path. We could change the name of Path
to _Path and use the code above to continue providing a Path alias, but that
might be too confusing. Another possibility is to pull those methods out into
top-level functions and then alias them into methods in WindowsPath and
PosixPath (perhaps using a decorator-like-thing to pass the flavor, instead of
attaching it to the class).
The main thing, though, is that Path should not depend on its subclasses. That
really strikes me as poor design, since it produces issues like this one.
