I thought about this too, but it occurred to me it's highly improbable
these were ever used, and I thought it shinier not to leave scars. But
if you feel strongly about it, no problem, I'll fix that up and send

It wasn't my intention to relitigate this, hence the rather short
commit message. You said your thing, Tomer said his, and now I'm just
trying to clear out the leftover soda cans.

I'll certainly be looking forward to reading analyses of HPolyC as
they come out.
