[Boost-users] [accumulators] chaining accumulator outputs

Is there a way to chain the output of an accumulator and use it as the input of another accumulator?

The sort of case I am thinking about is for example calculating the max of a rolling_mean. One obvious way to do this is to write a new rolling_mean_max accumulator and make it depend on rolling_mean, but the inner logic would be 99% duplicate of max. I was wondering if there was a way to do this without so much code duplication.
