Hi!

Without the help of Joaquín Mª López Muñoz I would not know about boost::tuples::element<N,Tuple>::type, which is a handy tool for library writers.

Can this be made part of the public interface of tuple and also be documented as such?

It's already there: http://boost.org/libs/tuple/doc/tuple_advanced_interface.html You'll be pleased to learn that it has also been integrated in the current C++ standard draft and is thus very likely to be part of C++0x . Cheers, Nicola Musatti
