Explore advanced metaprogramming techniques in modern C++ for library writers in this CppNow conference talk. Delve into creative approaches to implement metaprogramming idioms, working with the compiler to produce faster-compiling and more easily optimized code. Discover tricky uses of generalized constant expressions to optimize algorithms on heterogeneous sequences. Push the compiler to its limits and experience hardcore C++ dark magic in this 91-minute session designed for brave programmers ready to tackle cutting-edge metaprogramming concepts.
