And, Perl has an awesome community, let's not forget that. They do love clean code and all (modern Perl is very easy to read and understand IMHO), but are aware that in the end you want to get the job done.

Time and again, the question "are there any useful ideas or features in language X that we can borrow and implement in Perl?" has been posed by prominent people in the Perl community. Which is the opposite of the "not invented here" syndrome.
