> replace "dumb" uses of std::string with essentially the equivalent of what a smart C programmer using pointers would write Can you give an example?

  I am not op, but I do frequently feel like idiomatic C++ will create temporary copies of strings in areas where a C programmer would be less inclined to do so. For example, removing a prefix the C way would be to add the size of the prefix to the pointer. I guess c++ has string_views for that sort of case as of c++17.

      Yes, although it's not always your responsibility to do that. Firstly not all strings are on the heap, but ignoring that... If somebody passes you a pointer to a string and you aren't going to hold onto it for a while, you can just add to the pointer and it's no big deal. But yes, if you own the allocation, you need to keep the old pointer too.
