Setting up complex values for `Deno.bench` function runs

i was hoping i was being myopic and not seeing an option, but it looks like that is the case then 😐

Setting up complex values for `Deno.bench` function runs

there also don't seem to be any before() or after() hooks that one could hook into to set or reset state after each execution

Setting up complex values for `Deno.bench` function runs

so it doesn't really solve the problem.

Setting up complex values for `Deno.bench` function runs

actually... thinking about it now, the problem with that example is that the closure is only created once while the returned function runs many times, essentially having the same problem as an array outside the bench() scope

Setting up complex values for `Deno.bench` function runs

one idea that pops into my head is to write an IIFE that creates a closure and returns a function for bench() to consume:

Deno.bench('a', (() => {
  const data = getSample();
  return () => a(data, -1);
})());

Deno.bench('a', (() => {
  const data = getSample();
  return () => a(data, -1);
})());

but that looks a bit brittle and could easily be broken by omitting the parens at the end by mistake.
