C++17 Features (part 1 of 2)
summary
C++17 consolidates practical language changes: structured bindings let auto [x,y] = point3 to name members (and work with tuples/arrays); selection statements with initializers allow if (auto it = m.find(k); it!=m.end()) scoping; if constexpr enables compile-time branches and replaces some SFINAE/tag dispatch; fold expressions collapse variadic recursion into single operators; class template argument deduction plus deduction guides infer template types; inline variables fix ODR for header constants; guaranteed copy elision makes certain returns legal; constexpr lambdas and unary static_assert simplify metaprogramming.
