-// Outside help:
-// This and that, Gary Powell.
-// 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<>.
