Does it not contradict the premise of avoiding fields with abstract types ?

Yes, I guess you are right not to trust the newbie here

How to access shared "inherited" fields without paying multiple dispatch performance price?

Hi, I’m evaluating Julia to replace some old C++ code. The code uses inheritance where there is a single base class and lots (100’s) of derived classes. There are a large number of instances, and the code needs to be able to quickly get a base class field from a derived instance. I know that Julia does not have field inheritance and uses multiple dispatch to access data on abstract types instead. However, I’ve noticed that multiple dispatch methods slow down quite a bit for my use case when man…
