I've wanted to do that ever since I tripped over it implementing the original filetests in pugs; I know it can be done with some genericness but don't know enough win32 to do it.
One question is what to do with the non-generic stuff. For example, Win32 doesn't have symbolic links, but does have reparse points which are sort of similar if you squint; they're a superset of symlink functionality. (The closest thing Unix (not POSIX) has is mountpoints, but those are userspace aside from . and .. being the same inode. POSIX doesn't touch this space, IIRC, because there are POSIX implementations for Win32 (no mountpoints, some implementations may use reparse points to simulate them) and OpenVMS (no mountpoints).)
