Can you write up some preliminary proposal specifications? Here are some
useful resource/references to get started with proposal/spec authoring:

- https://github.com/tc39/ecmascript-asyncawait
- https://github.com/tc39/ecma402
- https://github.com/tc39/ecmascript_simd
- https://github.com/tc39/Array.prototype.includes

Thanks!

Rick
