That also would need a typecast since the function would return a parent 
class of the real class that was created, but the somehow the callee 
knows it's a descendent, so needs a cast to get to it (or use the "is" 
or "as" operators or ... etc).

This actually proves that a compiler error should also be required for 
the var/out parameter case as well.
