C++17 - The Best Features
summary
C++17 adds concrete tools and examples: inline variables let header-only globals share one counter so a header-only new tracker works without extra CPP files; constexpr if enables a single template function to compile different branches so impossible runtime paths never need to compile; variant with overload/deduction guides replaces pointer polymorphism with value types and easy visitors using combined lambdas; and combining filesystem with transform_reduce plus parallel execution cuts a real directory size walk time by about 50 percent.
