If we had declared `-> HeroPublic`, your editor and linter would complain (rightfully so) that you are returning a `Hero` instead of a `HeroPublic`.

By declaring it in `response_model` we are telling **FastAPI** to do its thing, without interfering with the type annotations and the help from your editor and other tools.

## Version 5.0.0-alpha.12

_2023-12-17_

We took too long to cut this release and there's a lot of changes in it. We've been busy.

Although this release is labeled _alpha_, the only unstable thing in it is our new APIs. This
release has many critical bug fixes and is safe to run in production. We're eager to stabilize our
new APIs so we can get out of alpha.

    return set;

  /**
   * Creates a <i>mutable</i> {@code HashSet} instance containing the given elements. A very thin
   * convenience for creating an empty set then calling {@link Collection#addAll} or {@link
   * Iterables#addAll}.
   *
   * <p><b>Note:</b> if mutability is not required and the elements are non-null, use {@link

 *   <li>As a convenience, the {@code main} of this class (JSR166TestCase) runs all JSR166 unit
 *       tests.
