As far as I can tell, Perl caches any inherited function lookups once they are performed, so after the first call, subsequent calls are just as fast as if they were in the class package. In the majority of cases, you can hardly tell the difference.

Using object-oriented methods incurs a small but acceptable penalty, and considering practical benefits, it's often worth the expense. An object-oriented approach is not always the most effective, admittedly, but it's often close enough that the differences are often a matter of preference.
