## Conversión automática

`Header` tiene un poquito de funcionalidad extra además de lo que proporcionan `Path`, `Query` y `Cookie`.

La mayoría de los headers estándar están separados por un carácter "guion", también conocido como el "símbolo menos" (`-`).

Pero una variable como `user-agent` es inválida en Python.
