I just have - evaluating a Legendgre polynomial 10k times at the same
point is just noise with both methods (of the order 10^-5 - 10^-4 s).

The Boost code is slightly slower because it doesn't cache the values
(which is nice not to do), but may be faster if the call is inlined.
It's not possible to inline it at the moment because of clashes between
tr1:tuple and boost::tuple (Boost bug, I suspect). Old and new are the
same when evaluating at different points.
