Nothing here sounds specific to strings other than naming. That's why it
seems like unnecessary specificity to me. IMHO, I would think

typedef contiguous_range< char > string_ref;
typedef contiguous_range< char const > string_cref;

would be better, and if you want an interface with names specifically
tailored to strings, make then free functions.

(And, no, contiguous_range does not exist in Boost, but given we already
have a model of it in the proposed string_ref, it seems like a simple
matter to provide it.)
