// 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)
