+// Fixed return types for get_head/get_tail
+// ( and other bugs ) per suggestion of Jens Maurer
+// simplified element type accessors + bug fix  (Jeremy Siek)
+// Several changes/additions according to suggestions by Douglas Gregor,
+// William Kempf, Vesa Karvonen, John Max Skaller, Ed Brey, Beman Dawes,
+// David Abrahams.
+
+// Revision history:
+// 2002 05 01 Hugo Duncan: Fix for Borland after Jaakko's previous changes
+// 2002 04 18 Jaakko: tuple element types can be void or plain function
+//                    types, as long as no object is created.
+//                    Tuple objects can no hold even noncopyable types
+//                    such as arrays.
+// 2001 10 22 John Maddock
+//      Fixes for Borland C++
+// 2001 08 30 David Abrahams
+//      Added default constructor for cons<>.

+// Revision History
+//  14 02 01    Remove extra ';'. Also, fixed 10-parameter to make_tuple. (DG)
+//  10 02 01    Fixed "null_type" constructors.
+//              Implemented comparison operators globally.
+//              Hide element_type_ref and element_type_const_ref.
+//              (DG).
+//  09 02 01    Extended to tuples of length 10. Changed comparison for
+//              operator<()
+//              to the same used by std::pair<>, added cnull_type() (GP)
+//  03 02 01    Initial Version from original tuple.hpp code by JJ. (DG)
