@mscdex Please check out the last benchmark results, they seem much better now.

Using an explicit constructor is necessary to avoid relying on
`Array.prototype[Symbol.iterator]` and `%ArrayIteratorPrototype%.next`,
which can be mutated by users.

Those don't show any perf regression either.

Be aware that when doing many comparisons the risk of a false-positive
result increases. In this case there are 25 comparisons, you can thus
expect the following amount of false-positive results:
  1.25 false positives, when considering a   5% risk acceptance (*, **, ***),
  0.25 false positives, when considering a   1% risk acceptance (**, ***),
  0.03 false positives, when considering a 0.1% risk acceptance (***)
