title: Use of binary_to_existing_atom(Binary, Encoding)
body: <p>I would like to convert some binaries coming from a socket to atoms that I will use later in gen_server calls. Since I don't want to flood the VM with new (and possibly non valid atoms) I use:</p>
  
  <blockquote>
    <p>binary_to_existing_atom(Binary, Encoding)</p>
  </blockquote>
  
  <p>Now, how (or better where) should I declare the valid atoms at systems startup so that the conversion will be valid? </p>
