Oh neat, thanks. I've been really scraping my head over this,
and was worried I wouldn't be able to keep supporting my D
version of the project.
Hmm... doesn't seem to operate at compile-time, which is an issue
if I want to use it in case switch table like I was going to:
--------------------------------------------------------------------------------
switch (queryInteger(childJson,"type")) {
case NodeType.Sprite:
child = this.addChild!(Sprite)(childName);
break;
default:
child = this.addChild!(Node)(childName);
break;
}
--------------------------------------------------------------------------------
