Hmm now that I think about it, I don&#39;t think this is really possible at compile time. You have to consider issues like multiple bases (Through either a linear chain of inheritance, or multiple inheritance cases).<div><br>
</div><div>If there were only a way to simplify this. Specifying the base class in two places is obviously error-prone, and I am hoping there are other solutions to cleaning this up.<br><br><div class="gmail_quote">On Tue, Jun 9, 2009 at 1:36 PM, Robert Dailey <span dir="ltr">&lt;<a href="mailto:rcdailey@gmail.com">rcdailey@gmail.com</a>&gt;</span> wrote:<br>
