Referencing new Scala 3 keyword using

The example code is correct. It's possible that we refer to givens generally as implicits. We still say "implicit scope" and not "given scope".

This section describes changes to the implicit resolution that apply both to the new givens and to the old-style implicits in Scala 3.

In recent PRs about the relative priority of givens and implicits, they are distinguished by their specific names.

Not sure if we say "using clause" now.
