### Resumen

En resumen, declaras **una vez** los tipos de parámetros, body, etc. como parámetros de función.

Lo haces con tipos estándar modernos de Python.

No tienes que aprender una nueva sintaxis, los métodos o clases de un paquete específico, etc.

Solo **Python** estándar.

Por ejemplo, para un `int`:

```Python
item_id: int
```

        .socket(peer.openSocket().asBufferedSocket(), "peer")
        .pushObserver(IGNORE)
        .build()
    connection.start(sendConnectionPreface = false)
    val queues = taskRunner.activeQueues()
    assertThat(queues).hasSize(1)
  }

  private fun data(byteCount: Int): Buffer = Buffer().write(ByteArray(byteCount))

  private fun assertStreamData(
    expected: String?,
    source: Source?,

import org.jspecify.annotations.Nullable;
