Detailed Description

Fallback implementation of the std::tuple class.

This a refined implementation of the approach defined in in the article "Tuples and multiple return values in C++" of Jaakko Järvi (Turku Centre of Computer Science, TUCS Technical Report No 249, March 1999, ISBN 952-12-0401-X, ISSN 1239-1891) available from the TUCS publications archive
