+// 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)
