That'd be messy if two things tried to take an iterator over the same scalar
as the same time. On the other hand if it created an iterator

Obviously I'd be honoured if it were, and this would prompt me to

My original plan was to sort all the faces from front to back and draw

Yeah, but I believe that at least Unicode has one of the four that they suggest
be used for non-locale specific comparisons (canonical decomposition form).
So pick that one for the core and provide the others (if necessary) as library
functions.

Do we want a Normalization function here as well. If you have that you can use a
binary compare (at least for eq/ne).

Subroutine, man, subroutine. NCI if you need it to be fast.
Feh on a subroutine--it's three or four ops with a few branches.
Which was the point--it eliminates the branches

Yeah, we probably do. The question is always "Which normalization"

I'm wondering if it'd be useful enough to be worthwhile to have
non-flowcontrol min/max ops. Something like:
min P1, P2, P3
max P1, P2, P3
where P1 ends up with the lesser (or greater) of P2 and P3.
On the one hand this'd make some of the code I'm generating now
simpler, but on the other i
