Not if we have interest in tuple from the Lambda Library.  I've 
suggested that this concept be submitted to Boost seperate from LL, 
and hopefully soon (I think it was held up by the hope to get support 
in VC++ for it, but I don't think this should hold it up any longer).

In case you don't know, tuple is similar to pair, but with arbitrary 
numbers of elements (fixed to a maximum N).  You supply the 
parameters in the template argument list.

tuple<int, char> tuple2;
tuple<int, char, float> tuple3;

Through meta-programming magic, such tuples are as efficient as hand 
coded versions for fixed numbers of elements.  The code even handles 
tie() for the N-ary tuples.
