Feature request

Is your feature request related to a problem? Please describe.
Related #2637

Describe the solution you'd like
Same as #2637

Additional context
My reasoning is that if TSLint permit this:

async function foo() {
  return 1;
}

const bar = () => foo();

then too should to permit:

async function foo() {
  return 1;
}

const bar = () => (
  foo()
);

with tslint.json configuration:

{
  "rules": {
    "promise-function-async": true
  }
}

Heya @localnet, I'm confused. #2637 was resolved by #4553. This feature should be available.

Is there a separate thing you're looking for? Specifically, what's the difference between this issue and #2637?

Excuse me if I have not explained myself well @JoshuaKGoldberg

Yes, #4553 solved the issue #2637 and permit this:

async function foo() {
  return 1;
}

const bar = () => foo();

But it don't permit this:

async function foo() {
  return 1;
}

const bar = () => (
  foo()
);

And to me seems it the same, practically (I use it, sometimes, to don't exceed the max line length).

Got it - totally reasonable. Thanks for the clarification! 😊
