> The basic_stringbuf(const basic_string&) ctor is an inefficient interface when constructing
a stringbuf object from a character array (as opposed to an already existing  string object).
Each invocation of the ctor causes a temporary string object to be allocated for the formal
function argument only to have it deallocated as soon as the stringbuf ctor returns.
> A basic_stringbuf(const char_type*) ctor overload would be a much more efficient interface.
> The same goes for the str(const basic_string&) member function of basic_stringbuf
as well as for all the stringstream class templates.
