34 /** \name Named tuples
35  It is often useful to declare little structures to aid in the passing
36  of arguments by name or returning sets of values. One can use
37  boost::tuples, but these don't have names for their parts and so
38  don't lead to clear code. Instead we provide a macro to aid
39  declaring such classes. The resulting class is hashable and
40  comparable too.
