title: syntax error, unexpected ',', expecting ')'
body: <p>I just installed Ruby 1.9.2 after having used 1.8.7, as there is a feature I need.  I had called many of my methods like this:</p>
  
  <pre><code>do_something (arg0, arg1)
  </code></pre>
  
  <p>With 1.9.2, i get the following error,  <code>syntax error, unexpected ',', expecting ')'</code> and the fix seems to be:</p>
  
  <pre><code>do_something arg0, arg1
  </code></pre>
  
  <p>But this could take me hours to fix all the cases.  Is there a way around this?  Why is it an error in the first place? thanks</p>
