title: condition || raise("error")
body: <p>I'm just wondering where this syntax documented:</p>
  
  <pre><code>1 &gt; 2 || raise("error")
  </code></pre>
  
  <p>I have tried use it as condition:</p>
  
  <pre><code>1 &gt; 2 || p "test"
  </code></pre>
  
  <p>but it doesn't work:</p>
  
  <pre><code>SyntaxError: (irb):9: syntax error, unexpected tSTRING_BEG, expecting keyword_do or '{' or '('
  1 &gt; 2 || p "test"
              ^
          from C:/Ruby193/bin/irb:12:in `&lt;main&gt;'
  </code></pre>
