You already can use boost::iterator_range<const char*>.
It doesn't provide the interface const std::string& provides and it doesn't solve the case for const void* (I think).

boost::iterator_range<const char*> is a sequence of bytes/chars, that is what pair<const void*,size_t> represents. It solves this case completely, but only that case. The reason it doesn't solve the const std::string& case is because there is no consensus of what interface std::string should have (see recent string discussions from about two months ago). As per the current std::string non-mutable interface, it includes only the find.* family of functions, substr, compare and c_str. Most of these are already handled by Boost.String and Boost.Range. They can work with interator_range transparently. The only problem is c_str, which I don't know how you want to implement it for string_ref anyway. -- Yakov
