Thanks.
I took a look at #1082, which reverted this one (and nothing else)
to see a test succeds, and then re-reverted it to see it fail (but
apparently only on FreeBSD/Cirrus).
I had an impression that it was claimed that without this, the other
weatherbaloon for "for (type var=..." would not fly in some of the
jobs we have at CI?
