[ddbeck]

Specification

• https://tc39.es/ecma262/#sec-iterator.zip
• https://tc39.es/ecma262/#sec-iterator.zipkeyed
• Normative: add Iterator.zip and Iterator.zipKeyed tc39/ecma262#3802
• https://tc39.es/proposal-joint-iteration/#sec-IteratorZip

Description

From https://github.com/tc39/proposal-joint-iteration:

takes an iterable of iterables and produces an iterable of arrays where position corresponds to position in the passed iterable

We'll need to find a way to say this doesn't cause semantic satiation on "iterable."
