I guess with the new & (I don't know of any compilers that have implemented it yet) feature we could have these overloads in path:
const string& string() const; string string() const &&;
so when a temporary path object is returned from path::extension(), the second overload is selected.
Interesting! I'm clueless about that use of &&. Need to do some reading.
Clang 2.9 and 3.0 have this feature (rvalue references for *this).
Thanks! That makes it practical to consider rvalue references for *this use in the interface. --Beman
