Yes. But I guess the original question was that why not a += (or +) 
operator implemented in accumulator_set  to add samples instead of 
operator().

Using std::accumulate to accumulate samples  (in an accumulation 
library) seems more natural to me than the functional implementation.  
And, using accumulate implies addition operators.
