I believe the explanation for not having a const char * casting operator is that since there is a const char * constructor the compiler would not know what to do when mixing the std:basic_string class with character constants in an expression since if you could convert both ways there would be ambiguity as far as which eay to convert and this would lead to a compiler error.
