I did an implementation for this proposal just for fun.
https://github.com/Jack-Works/TypeScript/tree/await.ops

  • Syntax: Basic support
  • Type: Basic support
  • Transpile: Downlevel to ES2020
  • Type: Support concrete tuple type
  • Type: Check if Promise.{*} exists
  • Syntax: Require a space after the operator? (Current impl await.all[array] is valid)
  • Service: Auto complete after await.
  • Service: Syntax highlight
  • Service: Refactor suggestion
  • Service: Hover quickinfo?
  • Type: Unique type error message

Screenshots:

In TypeScript, Promise.all has 10 generic signatures. If the array has more than 10 items in it, it will fail. The new syntax does not have this limitation.

Downgraded to ES2020, they are the same.
