Whether for validation, preparation, or splitting and sharing arguments, it can be quite annoying that Java doesn't allow statements before the `super(...)` or `this(...)` call in a constructor. Luckily Java 22 is about to change that with JEP 447, which previews statements before the explicit constructor invocation.
