Lambda the Ultimate

I recently wrote a book that deals with doing things (using features and ideas) in Perl invented and popularized by other languages. People react to that statement in fascinating ways - "what? Why would you want to do something in Perl that another language does? Perl is better so using things from Java and Python is pointless" they say.

I'm going to show first why quoted (paragraphased, actually) statement is dumb and then secondarily why it's a fallacy.

Yes, arguments of this sort still go on.
