“Implementing `static` control flow in C++14"
summary
Shows a working C++14 implementation of compile-time branching and looping that mimics C++17 if constexpr and adds a richer static_for with index, accumulator, break/continue and runtime side effects. Uses generic lambdas, variable templates and integral_constant wrappers, plus the for-args initializer-list trick and recursive lambdas to iterate. Demonstrates examples (consume, compile-time fold, static_for summation), compiles cleanly on GCC/Clang and emits zero-cost runtime assembly at -O, with measurable compile-time cost for recursion.
