In my code vararg functions not often [1]. And they have no
critical impact on performance. So (in my view) your benchmark
nicely exploits untypical case.

[1] History of style changes.

1. It looked ugly for me to write "for i = 1, select('#', ...)".
2. So I've started to write "arg = {...}" and for with ipairs().
3. And then it's occurred that more clear just to pass table instead
of sequence: "f(self, some, unknown, params)" vs
"f(self, some, {unknown, params})".
