Combining C++17 Features
summary
Shows concrete C++17 recipes: use compile-time if plus if-with-init and scope_lock to lock zero or many mutexes without deadlock; use class template argument deduction but beware brace-init traps that deduce wrong array types; replace recursive variadic templates with fold expressions to remove instantiation overhead; use string_view to avoid copies and speed a sort about 2.5×; use parallel algorithms and a tree-based partial_sum to get ~10× on many cores; use std::variant + visit + overloaded lambdas for value‑semantics polymorphism.
