title: Elixir interpreter error
body: <p>I was following <a href="http://elixir-lang.org/getting-started/basic-types.html" rel="nofollow noreferrer">elixir getting started</a> where it says run:  </p>
  
  <pre><code>iex&gt; i 'hello'
  </code></pre>
  
  <p>so I ran:  </p>
  
  <pre><code>iex(1)&gt; i 'hello'
  </code></pre>
  
  <p>and got:</p>
  
  <pre><code> ** (CompileError) iex:2: undefined function i/1
  </code></pre>
