  • avg() for getting the average over a list

    uniq() for returning unique values from a list

    uniq_ordered() for returning unique values from a list in the order that they were first seen

    stats() which will return max, min, ave, tot, count for a list

    See http://www.perlmonks.org/?node_id=407834 for background.

    • avg is already getting dangerously close to statistical functionality. Not that this would be fundemantally wrong in a list-module, but then people might come and ask for functions to calculate the quadratic mean or geometric mean as well.

      As for uniq and uniq_ordered, the first is no more computational work than the second from an XS point of view (as there are no hash-slices in C so one needs to loop anyway). uniq I could add.

      I am not convinced that stats is so terribly useful. max and min are already in
