That's a standard pattern for using a classmethod as an alternate
constructor -- similar to:
and it can really reduce namespace clutter (do you really want to import
both os and path for this? (OK, you way well be importing os anyway, but...)
It also allows you to get that functionality in a subclass.
Anyway, it's not that different, and I like it ;-)

indeed -- thanks for moving this forward, it is a long time coming!
By the way, for us dinosaurs is this going to exactly match the
pathlib implementation that can be used with py2?
