I just learned about [Eshell backticks][1].  So the first two lines can
be merged, even improving readability IMHO:

    $ setq my-files ${listify *.jpg}
    $ setq my-numbers $(number-sequence 1 (length my-files))
    $ setq my-pairs $(mapcar* 'cons my-files my-numbers)
    $ for pair in $my-pairs { setq a (car pair); setq b (cdr pair);
      mv $a "$b".jpg }

Now the question remains if there is a more terse way to do the rest of
the steps.
