How about a different motion that would generalize Motion 6 to
support midrad and other interval sets? (But some concepts, such
as the tightest FF-interval, would no longer exist.)
I'd prefer a motion to exclude midrad from consideration.
We have more than enough to do for infsup, and most considerations for
midrad are completely different than those for infsup, so that virtually
everything done for infsup would need to be reconsidered carefully.
As a result, the work load would nearly double.
Nobody in practice uses midrad as a basic representation,
except for input/output, where only the conversion behavior
needs to be specified, but not the arithmetic.
Midrad arithmeitc is used only (in Intlab) as a speedup mechanism
on the BLAS3 level, and doesn't need special standardization.
Moreover, putting BLAS2 and BLAS3 considerations into the standard
seems to me inappropriate.
