Me too! I worked on numerous C++ projects with such a string template class. It was usually called std::basic_string and came from this header called: #include <string> which also instantiated it into two flavors under two nicknames: std::basic_string<char> being introduced as std::string, and std::basic_string<wchar_t> as std::wstring. This class had a c_str() function which retrieved a null-terminated string and so most implementations just stored the data that way, but some of the versions of that class cached the length of the string to avoid doing a strlen or wcslen operation on the data. -- http://mail.python.org/mailman/listinfo/python-list
