Description

Finally, I so wish we could just do:

io::peek(request->socket, 6)
  .then([request](const string& data) {
    // Comment about the rules ...
    if (data.length() < 2) { // Rule 1
    
    } else if (...) { // Rule 2.
    
    } else if (...) { // Rule 3.
    
    }
    
    if (ssl) {
      accept_SSL_callback(request);
    } else {
      ...;
    }
  });
