This variant works strangely. Example:

abstract class Addon
{
        public string name = "0";
}
class Users: Addon
{
        override
        {
                public string name = "USERS";
        }
}
static final class Core
{
        static:
                public Addon[] activated;
                public Users users;
                
                public void activate()
                {
                        users = new Users;
                        activated = [new Users, new Users];
                }
}

Core.activate();
writeln(Core.users.name ~ "\n"  ~ Core.activated[1].name);

Out:
USERS
0

First of all, the code does not compile with override. It is 
impossible to override a data. Override should be removed.
The reason it works this way is that the first access is to 
base class data while the second is to the derived data member.

I don't need the base class data. How to create a array of 
subclasses objects with the derived data members?
