I understand that it's not possible to += all types of accumulated
statistics, but I will find it extremely useful to be able to do it for a
lot of stats that support this (count, sum, moment, covariance, more...).
Is there any way of using the accumulator_set interface to achieve the
equivalent of acc1 += acc2 ?
