Disallowing the creation of objects using new should have default object functions and parent functions be @nogc by definition.

It makes no sense otherwise. This logically implies that manual 
memory management is required, yet there is a possibility that 
the parent of the class may use the garbage collection. Which in 
this case, it begs the question on why the GC is forbid in the 
first place.

Does anyone dispute this?
