So you've discovered Rotate! I wish I could say
that there's a secret reward hidden ...
Yup, it's needed. Rotate was discussed last summer,
but got left out of the long July wish list. (I only went back
through my files a few weeks :-(
The generality is this:
ANY STRUCTURE OP IS VALID, AS LONG AS IT
LEAVES THE UNIVERSE IN GOOD ORDER.
(1-to-1 bidirectional connections.)
Or perhaps we could say (nostalgically):
"If it feels useful, do it!"
Best, Ted
