Stroustrup: “Every single word about “token comparison” is there to workaround absence of a real module system” Safety: - A toolchain should try its best to diagnose ODR violations e.g. linker errors types Speed: - Matching a function call to its definition begins “the great hunt” ## The Global Module ■ Everything we used to do before Modules - Merry mess ■ Provide no ODR guarantees – Responsibility making up a component ## Module Ownership ## Module Ownership - Supporting programming in the large (componentization) - Non-interference between module-local entities (module linkage) - Interface

You can set the floating point mode in a struct or module scope by using a comptime block.
