title: Telethon send messages in list in asynchronous manner
body: <p>Sorry for any broken english...</p>
  <p>So, basically, I have a list containing messages and their destinies:</p>
  <pre><code>messages = [(id_1, msg_1), (id_2, msg_2), (id_3, msg_3),]
  </code></pre>
  <p>What I want is to use a: <code>async for msg in messages</code> however, my list, obviously, isn't asynchronously iterable (I am using sqlite3) how can I convert it to a asynchronously iterable list?</p>
