Benedict Elliott Smith commented on CASSANDRA-15394:
----------------------------------------------------
(y)
I think there's some value in introducing {{isize}} as a norm, only because
when we have nested loops the norm will have to shift, but it's also pretty
simple for somebody to switch to {{isize}} and {{jsize}} in this case. It
seems fine to use plain {{size}} when there's only one loop.
