À ne pas confondre avec la déclaration de valeurs par défaut comme ici :

```Python
    first_name="john", last_name="doe"
```

C'est une chose différente.

On utilise un deux-points (`:`), et pas un égal (`=`).

Et ajouter des annotations de types ne crée normalement pas de différence avec le comportement qui aurait eu lieu si elles n'étaient pas là.

   * Returns the escaped form of the given Unicode code point, or {@code null} if this code point

 * information among plugins, is this more like an extension point - do we need a sort of bus for
 * application data - do we need a dictionary for our applications like Apple does. We could easily
 * hook into this and this is the model we need to follow - how many of our REST services do not map
 * directory to a method in the application interface?

 * - research extension points versus plugins
