Tenho evitado criar um novo framework por anos. Primeiramente tentei resolver todos os recursos cobertos pelo **FastAPI** utilizando muitos frameworks diferentes, plug-ins e ferramentas.

Mas em algum ponto, não houve outra opção senão criar algo que fornecesse todos esses recursos, pegando as melhores idéias de ferramentas anteriores, e combinando eles da melhor forma possível, utilizando recursos da linguagem que não estavam disponíveis antes (_Type Hints_ no Python 3.6+).
