\subsection{Can I Create Messages Dynamically?}

Yes.

Usually, messages are created implicitly when sending messages but can also be created explicitly using \lstinline^make_message^.
In both cases, types and number of elements are known at compile time.
To allow for fully dynamic message generation, \lib also offers \lstinline^message_builder^:

\begin{lstlisting}
message_builder mb;
// prefix message with some atom
mb.append(strings_atom::value);
// fill message with some strings
std::vector<std::string> strings{/*...*/};
for (auto& str : strings)
  mb.append(str);
// create the message
message msg = mb.to_message();
\end{lstlisting}
