* Avoid deep copy of vectors (technically more than a cleanup). * Use `std::make_unique` for allocating unique pointers, rather than manual `new`. * Use `std::optional` for optional by-value return values, rather than C-style `bool` to indicate success + return-argument. * Use references rather than pointers for non-optional arguments. * Avoid manual `new`/`delete`. Use `std::unique_ptr` for local scope bound lifetime. * Use C++ `nullptr` rather than C's `NULL`. * Remove unnecessary friend declaration. These changes are generally considered good practise and move us more to a "modern C++" style. We can still go much further of course.
