Agreed. Adding my take to the "intended audience discussion", I expect that my co-workers have a solid grasp of Perl, so I don't shy away from using somewhat more complex Perl idioms.
Published papers in mathematics don't explain the summation symbol every time it comes up. If you have a degree in mathematics, you're just expected to understand it already. Likewise, there's no reason to limit yourself to a pidgin dialect of Perl (or any other language) if you're hiring good people.
