// If the tuple implementation changes, all that needs to be
// replaced is the implementation of these four (meta-)algorithms.
//
// Unfortunately, some compilers, including Metrowerks Codewarrior
// 4.2.5.766 and gcc 3.3, were unable to handle the template
// code involved (Metrowerks: internal compiler error, gcc 3.3:
// segmentation fault). Therefore, rather regrettably, for those
// compilers, the encapsulation of the tuple implementation-
// specific code is not nearly as nice and clean as it should be.
// In order to emphasize this point, I have provided the entire
// namespace detail in this file twice: the first version is the
// clean one with the nice encapsulation, the second one is the
// dirty one.
