Object-oriented code not use virtual functions much? If you don't need virtual functions, then use a struct, not a class. Classes are polymorphic. Structs are not. In general, it doesn't make a lot of sense to use a class in D if you don't need polymorphism. And if you do need to but don't want the functions to be virtual (e.g. you want to use a class, because you want a reference type without going to the trouble of making a struct a reference type), then you can just make all of the class' public functions final. But that's not the normal case at all. - Jonathan M Davis
