This part is not going to work, so you can leave it out from this PR.

I believe this is still slow, even with V8 5.4 currently in master.
Ditto for the other rest args uses.

Have you performed benchmarks that tests these changes? |

This change will likely be difficult to backport, just changing it is of little value.... was anything else improved? Can it be improved without using |

-1 on this for the moment. Large rewrites like this across the code base are prone to error and make debugging harder as it will completely wash the blame on the document. There are also potential performance concerns as mentioned by @mscdex further, since it is semver major, this is going to make any backporting unnecessarily difficult What are the reasons for the change aside from adopting new features |
