Quinn already said the most important things, but I'll note another best
practice (according to me, anyway).

People often think that the "shebang" line is how you start a Perl
program. Not so! All true Perl programs start with a 4-line preamble:

    #!/usr/bin/perl -T

    use warnings;
    use strict;

A file beginning with anything else is actually program text in some
other, inferior language. ;) If taint checking, warnings and strict
cause Perl to print any warning or error messages, you definitely have a
bug that you must fix.
