std::string has no problem handling this! You can even store really long strings in a std::string. This is one of the reasons that std::string is so powerful. Key insight If std::string doesn’t have enough memory to store a string, it will request additional memory (at runtime) ...

I am going to answer myself: std::basic_string shouldn't inherit std::vector; it should have a std::vector member if it has anything to do with vectors and wrap thinly around it for similar methods. It would seem, however, that all the functionality similar to std::vector is reimpleme...
