Sonraki request'lerde dependency'ler içinden `get_settings()` çağrıldığında, `get_settings()`'in iç kodu tekrar çalıştırılıp yeni bir `Settings` nesnesi yaratılmak yerine, ilk çağrıda döndürülen aynı nesne tekrar tekrar döndürülür.

It can't handle nested models very well. So, if the JSON body in the request is a JSON object that has inner fields that in turn are nested JSON objects, it cannot be properly documented and validated.

Body-Schemadefinitionen verwendeten nicht die gleichen Python-Typhinweise wie Pydantic, er war Marshmallow etwas ähnlicher, sodass die Editorunterstützung nicht so gut war, aber dennoch war APIStar die beste verfügbare Option.

Er hatte zu dieser Zeit die besten Leistungsbenchmarks (nur übertroffen von Starlette).
