I believe that features like variadic friends, advanced template metaprogramming techniques (including concepts and ranges), and even constructs like coroutines and lambdas with auto return type add layers of complexity to C++. While these modern features can be powerful, they often contribute to an increasingly steep learning curve and may sometimes obfuscate rather than clarify the code. Instead of chasing developers away with such intricate additions, the language would benefit from focusing on practical enhancements that address everyday challenges. For instance, incorporating built-in package management or native support for common data formats like XML and JSON would provide real, tangible benefits. These kinds of improvements could help modernize C++ without overwhelming developers with complexity.
I love how mind-warping modern C++ can be, but this feels like another pattern I would exhaust myself trying to explain in an MR in my more conservative shop.
