Note that use v5.36; disables this ancient Perl-4-style multidimensional array emulation

Thanks for the heads up eyepopslikeamosquito :)

Now that I know where to store modules thanks to haj, it's my intention to rewrite this legacy code and remove the current repetition. Looks like I might have to move that up the todo list...certainly before I upgrade to Perl v5.36.
