This argument is not helpful to understanding c++ capabilities. Turing completeness already says we can implement anything in any of these systems, even if it means implementing the other system. We are talking about how different languages solve problems in their native constructs, not what one can theoretically implement (which is the same for all turing complete languages). What we are talking about is how the native language structures are handled by the runtime. In known C++ compilers, base class size, vtable layout, parametric instantiation and instance variable layout are hard coded at compile time. In objc/swift/clr/java, these are all resolved dynamically at load time. This enables many binary compatible dll updates which are not possible in c++ (* when actually using c++ language features)
