For the moment, you're probably screwed. Certainly, if you overload opCast, then none of the normal casts work any more, which is a definite bug: http://d.puremagic.com/issues/show_bug.cgi?id=5747 So, unless there's a way to do it without a cast, you're stuck. And I have no idea how you could possibly do it without a cast. - Jonathan M Davis
