The vertical bar is supposed to satisfy that need. I fixed a bug that prevented x|-y from working similarly to x--y: it was scanning the piece name for | and - in the wrong order (- first), and would then test whether another - followed, to replace it by the first prefix.
The < and > are only needed for sideway rotations.
