Unravelling `Async for` Loops

A little more verbose than your example but https://github.com/tc39/proposal-async-do-expressions would help with this.

Thanks! I think it wouldn’t await the whole loop though

  for (const item of iterable)
    async do {
      await item()
    }

This would be equivalent to

  Promise.all(arr.map(async item => {
    await item()
  })

Notice the lack of await before Promise.all
