[Python-ideas] Better stdlib support for Path objects

[Antoine Pitrou]

Hi,

Not inheriting from built-in classes such as str, list or tuple
was one of the design points of pathlib. It will not change in the
future ;-)

PEP 428 outlines this, but you can probably find a more detailed
discussion in the python-ideas archive.

Regards

Antoine.
