@kixik Inheritance can always be substituted by composition which is what #Rust does pretty well. Constexpr isn’t on C++ level, but I guess you can generate code from build script so there’s ways around it.
As for virtual functions - Traits are effectively to virtual function lookup table declarations that get used by dyn SomeTrait type. So calling a fn on Box\<dyn T\> generates VMT lookup.
