The Three Little Dots and the Big Bad Lambdas
summary
Claims that C++14/17 idioms actually replace heavy TMP with generic lambdas and pack tricks, showing concrete idioms: std::integer_sequence and pack expansion plus fold/for-init forms to build an arbitrary code unroller and a tuple for‑each. Prototype composes lambdas to inject code and emits fully inlined calls, but sometimes requires forced inline and makes debugging noisier. A pure‑C++ matrix–vector kernel is built and measured, matrix–vector kernel matching OpenBLAS performance on several targets (with caveats about cache and prefetching).
