Ah, yea, actually if I scroll down a little in the editor I see it gives an
example of each case (8/24 for the first case, and 5/5/5/1 for the second
case).

Yea, I guess thinking about it more, even if we can get scalar fetch to work
with sufficient twiddling, that twiddling probably introduces extra operations
per element, so maybe not a good idea. I guess we should take another crack at
attachment 131000 first.
