Until now it didn't: it was taken as an instruction to execute, i.e.
(benchmark-run nil (setq m (1+ 0)))
is treated as
(benchmark-run 1 (progn nil (setq m (1+ 0))))
rather than
(benchmark-run 1 (setq m (1+ 0)))
It just happens to do the same. The same holds for
(benchmark-run (+ 3 4) (setq m (1+ 0)))
which behaves like
(benchmark-run 1 (+ 3 4) (setq m (1+ 0)))

Oh, right, I did miss this one, thanks,
Stefan
