Fold expressions

The C++ 17 standard added support for fold expressions to ease the generation of variadic functions. The Compiler does pattern matching and generates the code by inferring the intent of the programmer. The following code snippet demonstrates the idea:

Ts>auto AddFoldLeftUn(Ts... args) { return (... + args); }template <typename... Ts>auto AddFoldLeftBin(int n,Ts... args){ return (n + ... + args);}template <typename...
