* Add ["Typed Macros"](https://github.com/leanprover/lean4/pull/1251): syntax trees produced and accepted by syntax antiquotations now remember their syntax kinds, preventing accidental production of ill-formed syntax trees and reducing the need for explicit `:kind` antiquotation annotations.

```lean
