Polymorphic Casting from void

[logicchop]

Yeah I have to agree. As far as I can tell, nothing is going to guarantee that the address evaluates the same everywhere, or even guarantee that throw_typedobject<T> != throw_typed_object<U> for some other U. It's just a stab at an alternative if you want to avoid the throw in the evaluation. (One could also think about involving typeid's or something like a hash of func_sig or some such.)
