Your code is not very D style and, based on your needs, there may
be better ways to achieve your goal, but without knowing your use
case, it's difficult to give correct advice.
Talking about that writeln statement, your code is not working
because of a known compiler bug [1]. If you change your interface
BaseVector to an abstract class and add the needed override
annotation to GenericVector, then typeid returns the expected
result.
