[Feature Request]: Add promise resolving in REPL

Description

Currently when using REPL for debugging some library's async methods is painful

> asyncTaskThatResolvesNumber();
Promise<pending>

// nodejs repl
> await asyncTaskThatResolvesNumber();
await asyncTaskThatResolvesNumber()
^^^^^

Current workaround is

> asyncTaskThatResolvesNumber().then(console.log)
123

Desired Behaviour

Chrome's console handles the case as follows.

> asyncTaskThatResolvesNumber();
Promise<pending>

// chrome console
> await asyncTaskThatResolvesNumber();
123

It'd be very helpful if we can do that in NodeJs REPL.

TLA in REPL has been supported experimentally behind flag --experimental-repl-await. You can enable it with node --experimental-repl-await.

Wow that's awesome! Thank you. So I shall close this.

Though is it known approximately until when this will stay experimental? Because it seems that it works great.

There is no ETA to unflag this right now. In the discussion on #34733, it seems still too early to unflag.
