Aahh, we needed a macro instead:
(defmacro bench (&rest forms)
"Convenience wrapper for benchmark-run-compiled."
`(let ((n 10))
(/ (nth 0 (benchmark-run n ,@forms)) n)))
This gives a reasonable difference in performance.
By the way, does elisp lists have extra pointers to the middle of the
list (a skip-list)?
