As data driven systems evolve there's an ever growing demand for bringing new functionality into existing systems in an efficient, maintainable and least intrusive manner. When implementing features with different semantics or interfaces, virtual inheritance requires a compromise between design simplicity and performance. This implies a need for new techniques to achieve heterogeneous polymorphism efficiently. With C++11 and 14, type lists, type maps and variants can now be trivially implemented by the initiated. Facebook moves fast so we quickly adopted the new standards to further explore the capabilities of the type system. This talk demonstrates some meta-programming techniques like reflection and compile-time built structures to achieve heterogeneous polymorphism and fast prototyping.
