Il réalise quelque chose de similaire à ce qui peut être fait avec Flask-apispec.

Il possède un système d'injection de dépendances intégré, inspiré d'Angular 2. Il nécessite de pré-enregistrer les "injectables" (comme tous les autres systèmes d'injection de dépendances que je connais), donc, cela ajoute à la verbosité et à la répétition du code.
