I appreciate that.. but I would think a mechanism as fundamental as 
qobject_cast<> should be specified with the same rigor as dynamic_cast<> in 
C++. Even if just to add a line to the docs "if you pass 0 the behavior is 
undefined, don't do it!" -- at least then I would know to not call it with a 
0 parameter (even though I can do that with dynamic_cast). These kind of 
edge cases are where the bugs often happen as you know.

Thanks!

Ross.
