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.
