[In the path library] the `Path` has different representation on Windows and POSIX which seems that no way to use both on the same platform

IMHO it will be good to have like in Python: all kind of paths (NT, POSIX, etc) available as well as local path (local platform dependent)...

Why like in Python? You mean like in Haskell. The standard and popular "filepath" library in Haskell does all that very nicely. The "path" library you are looking at is a newer library that wraps "filepath" and provides more type safety. It looks very nice. I hope the issue with multiplatform paths will soon be fixed, and then perhaps the path library will become more widely used. In the meantime, I suggest you use the "filepath" library. Regards, Yitz
