## I mplementing C++ Modules: Lessons Learned, Lessons Abandoned Gabriel Dos Reis & Cameron DaCamara Microsoft ## Overview ## C++ Modules Design Goals 1. Componentization - Compositional semantics your friend - Named modules provide ODR guarantees, by design - Header files and header units require (expensive) incomplete ODR checks, and demand complete trust ## Modules and ODR ## One Definition to its definition begins “the great hunt” ## The Global Module ■ Everything we used to do before Modules - Merry mess ■ Provide no ODR guarantees – Responsibility of the programmer Complete ODR check
