This broke in 7bcc947. @timholy, any idea about how to fix this?

[timholy]

Yeah...fix my buggy implementation of iterstate for CartesianRange iteration. Gotta run now, though.

[tkelman]

if this breaks any user code, should I revert #13235? 0.4.1 needs to go out imminently.

[timholy]

No, because it fixes so many more breakages than it causes. Fix coming momentarily.
