Actually, the compiler message is technically correct, but rather unhelpful.

For the casual user, it is enough to say that in an assignment, the LHS 
and the RHS must have the same type. In your case, the RHS is of type 
Shape'Class, therefore the LHS must be of type Shape'Class (possibly 
thanks to a conversion).
