### "`.await` does not perform autoref or autoderef" rust#111546

**Link:** https://github.com/rust-lang/rust/issues/111546

CE: I'm not particularly compelled by this, especially due to the implicit `into_future` that takes `self` by value. And there's some danger of this complicating inference.

https://github.com/rust-lang/rust/pull/111773

CE: The inference danger I predicted did show up in that crater run.

https://github.com/rust-lang/rust/pull/111773#issuecomment-1555357572

CE: The least we need to do here is to fully analyze this crater run (much more than has been done to date).

CE: We'd need to do this over an edition, and then we'd have two implementations of the `.await` operator.

CE: Postfix macros can't autoderef. It doesn't make sense for postfix match either. Match already has match ergonomics.

let x = String::new();
match x {
    "" => {}
    // is equivalent to:
    deref!("") => {}
}

x.match {
    "" => {}
}

TC: Consistency with postfix macros does seem compelling.

CE: Indeed, it is essentially a postfix macro.

### "Initial support for auto traits with default bounds" rust#120706

TC: We triaged this above.

### "Add simple async drop glue generation" rust#121801
