This migration is again a (typed) macro that the compiler can automatically apply to any matching call site whenever it upgrades a dependency from a previous version to 1.2.3. If the Rust compiler were smarter, it could automatically fix issues like this by inserting type annotations in any code that was previously unambiguous!
