The latter. And the "name" would always be the same (it would only
change in the next iteration; but for a given iteration, all names would
be the same).
So essentially, as I wrote:
some-name-10
some-name-9
some-name-102
some-name-89
with the result:
some-name-9
some-name-10
some-name-89
some-name-102
But I think "sub extract" discussed earlier is simple enough for this
case, and I used it.
