It *is* boost tuple. Jaakko and I worked on it. It is based on Jaakko's
TR1 proposal. The new tuples implementation overcomes the problems
and limitations of the current boost tuples. Recently, I added iterators,
sequences and algorithms, such that it is very similar in structure to MPL,
except that it works on the twilight zone between compile time and runtime.
