Can we move this to stage 2?
- We have a spec draft:,
- We have champions: Gorkem Yakin, Nozomu Katō and Brian Terlson
- I'm pretty sure this is going to be part of the standard according to the
last TC39 meeting.
- There is a fully functional implementation in the newest V8, though
behind a flag at the moment.
- There is another polyfill implementation: (dart, but can be
transpiled into JS)
