title: In Erlang, when do I use ; or , or .?
body: <p>I have been trying to learn Erlang and have been running into some problems with ending lines in functions and <code>case</code> statements.</p>
  <p>When do I use a semicolon (<code>;</code>), comma (<code>,</code>), or period inside my functions or <code>case</code> statements?</p>
