How is this different from (say) contiguous_range< char > / contiguous_range< char const > ? I can imagine a contiguous_range<T> that wraps a pair of T*s, which would seem to be a simple generalization of your proposed string_ref.
It isn't. The only difference is that string_ref provides an interface for substring operations, similar to std::string but without returning copies of the data, hence the string in the name.
That'd be better as a non-member function, wouldn't it?
It arguably would, but that wouldn't mimic std::string's interface. I'm talking of stuff like string_ref a = "foobar"; string_ref b = a.substr(2, 4); assert( b == "obar" ); This is somewhat equivalent to the same code without the "_ref", except the above doesn't actually copy anything (modifying b will modify a). See the paper for more info.
