What are you trying to achieve with the compare? Depending on the answer an array, a hash or a database may be a good answer, or maybe you don't need to store anything at all. In no case should you need nested loops that run across all combinations of element pairs however.

There is no "one best solution" for all problems. Having a good understanding of what you are trying to achieve very often will point you toward the correct data structure and once you have the data structure right very often everything else just slots into place around it.

Perl is the programming world's equivalent of English
