What are you talking about? If Grandfather's code works, then my code should work as well because it is just a trivial refactoring. If it does not work, then I guarantee that it is the result of a silly typo and not a result of my not understanding how to use references in Perl. If I've done something you don't understand, the odds are higher that I understand something about references in Perl that you don't, than the reverse.

If you doubt my competence, I suggest that you browse 10 or 20 of my best nodes. (You might want to skip the first couple, at least half of the top 10 don't have real programming meat.)

On using type as a constant, the usual convention is that constants should be ALL_CAPS. It doesn't matter to Perl, but you are violating expectations there.
