@augustohp how it's no make sense?
I have a class receiving a `Response` already configured, and call a method named `send()`, I think it's obviously, because a response is formed by your body too. 

And on async things, I think if is not a surprise, is common expect any body response on various APIs.

I'm wrong?

What @jackmakiyama think about that?
