It's an interesting proposal, but unfortunately there's the possibility of an n:1 mapping between parent directory and child.  This would make using ".." against the current working directory potentially non-deterministic, and removing lower elements from an absolute path wouldn't necessarily get you back to the directory where A.hs lived either.
