Phew, this was the hardest of them all...

@bnoordhuis Proposal: aftewr this lands, I'll update some docs and cut a release.

Then do a bit of cleanup, I see some opportunities to DRY some code. WDYT? Anything else you'd like to do before releasing?

I'd like to fix #683 (should be trivial) and I've been thinking about releasing amalgamated builds but that doesn't have to hold up this release. I'll open an issue to discuss.

Oh, I guess we still have a few Iterator failures in test262_errors.txt, with a few more after updating test262. Maybe they're harmless but it'd be good to look into them before cutting a release.

I'll take a look. Some of them were there before and some were fringe cases but I'll double check!
