Thank you as well for the very quick response!

The reason I did y $ref_array = @_ was because I was passing an array reference to the subroutine but didn't make the connection between the scalar assignment (which is what I did) and list assignment (which is what I should have done).

I don't think I will ever post a non-reference-related question here based on my history but I swear, I am trying!

    I use the list assignment mantra as a matter of course when accessing parameters passed into a sub so anything else as the first line of the body of a sub looks strange to me. Doing the parameter assignments in a single hit up front makes it easier to see what should be passed into the sub. Getting into the habit of solving the same problem in the same way is often a Good Thing.

    Optimising for fewest key strokes only makes sense transmitting to Pluto or beyond
