A couple of questions:

  1. Why pass in a reference if the first thing you are going to do is copy the reference array to a local array? 
    sub check_arrays {
     my @full_array = @{shift()};

  2. Why make a local copy of the array at all, when all the uses (join, sum, sort) of it require you to pass a list?

    Ie. Why not my $sum = sum @$ref; etc.

  3. Isn't re-summing your partial array over and over wildly inefficient?

In the absence of evidence, opinion is indistinguishable from prejudice.
