title: late static binding: which languages commonly used for web development support it?
body: <p>Lately I've been seeing a lot of talk regarding PHP's lack of late static binding until 5.3. </p>
  
  <p>From what I've read proper implementations of stuff like ActiveRecord are not possible until the language has this feature.</p>
  
  <p>So, I'm curious about:</p>
  
  <ul>
  <li>Which languages do support it,
  specifically those commonly
  associated with web development such
  as Python, Ruby, Perl, Java, C#,
  (JavaScript?).</li>
  <li>Which actually make use of it on a
  regular basis?</li>
  </ul>
