Yes.

The accumulator doesn't store it. E.g., if you are accumulating the sum,

So, I still have to keep the samples in a std::vector.

Then, a second question. I store the samples in a std::vector. What is the
most efficient (time point of view) : use the std::vector of samples and
std::for_each (as mentionned in the doc), or build the accumulator_set in
conjunction with the std::vector ?
