Hello everyone,
I=E2=80=99d like to ask for your help regarding the syntax.

**Goal:** I want to get rid of the `BoundedScope` object while still
providing a convenient built-in tool for controlling wait time.

To achieve this, we could extend the `await` expression so that it allows
explicitly specifying a limit.
For example:

```php
await $some with 5s;
```

Or a more general approach:
```
[<resultExp> =3D ] await <AwaitExp> [bounded <CancellationExp>];
```

I=E2=80=99m concerned that no other programming language has a similar cons=
truct.

On the other hand, if `Cancellation` is defined in a different way (not
through syntax), it requires a separate function. For example:

```php
await all([$task1, $task2], $cancellation);
```

This approach is actually used in all other languages.

My question is: Should cancellation have its own syntax, or should we
follow the conventional approach?
