If this is all you need, just use plain references.

OK. I thought you were talking about Olaf's desire to have implicit conversion from std::string. For this we use just f(char_range::literal("Olaf"))**;
basic_string_ref<T> is meant to when being implicitly constructed from a T(&)[N] or T const* that it is null-terminated.
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? -- Yakov
