I know there are overheads to calling subs, but did not think they were sufficiently large that inline code runs millions of times per second while code refs run at fewer than ten times per second.

Purely out of curiosity, are the process and overheads documented anywhere? I can think of things like setting up @_ and other bookkeeping processes, but perhaps there are other steps.
