Finally. But don't believe the python/perl comparison troll, as
python, for once, actually outguns perl on a character chomping basis,

sub pairwise_sum ($arg1, $arg2) {
    return map { $arg1->[$_] + $arg2->[$_] } 0 .. $#$arg1;
}

def pairwise_sum(list1, list2):
    return [i + j for i, j in zip(list1, list2)]
