C++ Modules Myth Busting

on YouTube ↗26m

" summary

Demos show three concrete wins: strong ownership lets the linker disambiguate two module definitions (answer() = 42 vs 41) and supports a linker-switch to disable weak-fallback; include translation rewrites #include to header-unit imports and is used with MSVC header units and IFC files to avoid ODR errors; practical builds with CMake + Ninja show a single-file rebuild dropping from 1.3s to 0.11s (~10x), Office migration reports ~20% end-to-end speedup and IFCs ~10x smaller than PCH.
