I think you should edit the wiki and add them, because here your message will be lost between all the flux of messages.

The last example:

override bool opEquals(Object rhs)
{
    // the other must be at least a Widget
    auto that = cast(Widget) rhs;
    if (!that)
        return false;
   // do they compare equals as Widgets? if not, we're done
    if (!super.opEquals(that))
        return false;
   // is it a TextWidget?
    auto that2 = cast(TextWidget) rhs;
   // if not, we're done comparing with success
    if (!that2)
        return true;
   // compare as TextWidgets
    return text == that.text;
}


Last return should be:

return text == that2.text;
