I don't think this one is worth arguing, because its probabaly unattainable anyway. The problem isn't controlled types per se. The problem is that you can't derive from a type at a lower level than the parent is declared. If you implement your components with tagged types, you will almost certinaly bump into this limitation whether controlled types are used or not. --- T.E.D. homepage - http://www.telepath.com/dennison/Ted/TED.html No trees were killed in the sending of this message.
