Reverse scan

-

We've discussed how the scan moves forward along 𝕩, so that each time 𝔽 takes an old result as 𝕨 and a new value as 𝕩. This means that results correspond to prefixes and go left to right on each one. Since the most important scans have associative, commutative operands, the left-to-right ordering often doesn't make a difference. But sometimes a suffix rather than prefix scan is wanted. For these cases, Scan Under Reverse (`⌾⌽) does the trick.
