I'd say the problem you mention needs only be considered in the
filesystem case where you have the interpretation of a path as
referring to a symlink. If we're just considering the path, then the
parent of the path /x/right1/right2/bar is /x/right1/right2. If you
want the filesystem interpretation, then you want
path("/x/right1/right2/bar")/"..", which will act equivalently to /x
in operation functions.

I think, as a decomposition function, the name parent is sufficiently clear.
