Contrast it with async in JS/ES as an example... now combine it with the using statement for disposeAsync instances.

    await using db = await sqlite.connect(await ctx.getConfig("DB_CONN"));

It's not so bad when you have one `await foo` vs `foo.await`, it's when you have several of them on a line in different scopes/contexts.

Another one I've seen a lot is...

    const v = await (await fetch(...)).json();
    

Though that could also be...

    const v = await fetch(...).then(r => r.json());

In any case, it still gets ugly very quickly.

I'll give my two cents here. I work with Dart daily, and it also uses the `await future` syntax. I can cite a number of ergonomic issues:

```dart (await taskA()).doSomething() (await taskB()) + 1 (await taskC()) as int ```

vs.

```rust taskA().await.doSomething() taskB().await + 1 taskC().await as i32 ```

It gets worse if you try to compose:

```dart (await taskA( (await taskB( (await taskC()) as int )) + 1) ).doSomething() ```

This often leads to trading the await syntax for `then`:

```dart await taskC() .then((r) => r as i32) .then(taskB) .then((r) => r + 1) .then(taskA) .then((r) => r.doSomething()) ```

But this is effectively trading the await structured syntax for a callback one. In Rust, we can write it as this:

```rust taskA(taskB(taskC().await as i32).await + 1).await.doSomething() ```

I was a proponent of the postfix macro solution. `.await!` or `.await!()`, essentially. The idea was that this could be generalized, it was closer to existing syntax, etc.

I was worried about features that I still don't love like `.match` etc (I'm more open to these now).

Post-fix macros would have been very complex. Scoping alone is complex.

`.await` kinda just works. It does everything you want and the one cost is that it looks like a property access but it isn't. A trivial cost in retrospect that I was a huge baby about, and I'll always feel bad about that.
