Detailed Description

A non-owning string class (similar to the forthcoming std::string_view) Note that, because a StringRef may be a substring of another string, it may not be null terminated.

c_str() must return a null terminated string, however, and so the StringRef will internally take ownership (taking a copy), if necessary. In theory this ownership is not externally visible - but it does mean (substring) StringRefs should not be shared between threads.
