Important point! Current wording does not require the string_ref to point
to a null terminated string. This (a) enables working with substrings, (b)
makes it unclear how it is better than iterator_range, and (c) does not
solve the problem for the fstream::fopen(const char*/std::string&) case.
Do you really think that trading (c) for (a) is a good idea?
