This does raise a concrete API design question: how should PurePath.fspath behave when called on a mismatched OS? I think that PurePath.fspath should return a string. There’s no reason why we can’t in my opinion and doing so just limits the usefulness of the method. For instance, it’d prevent it from being possible to serialize a pure windows path and send it over the wire to a process running on a Windows machine, like say if you have a build master running on Linux and a build slave running on Windows.

Yeah, given that you have to go out of your way to create a path object for an alternate platform, this makes sense - the "I know what I'm doing" indicator is calling pathlib.Pure[Windows|Posix]Path instead of ""pathlib.PurePath in the first place, and so fspath can just do its thing as a pure text-based operation, without worrying about the current platform.

Cheers, Nick.
