Hello,

Having a list of doubles stored somewhere, is there a way not to copy the
doubles into the accumulator set and just iterate somehow through the
existing data in order to save memory.

Imagine I have a std::vector<double> with 10million entries.

Then pushing each double to the accumulator set object, then I'd imagine, at
one point, the process would hold the 10 million doubles twice.

Rds,

MM
