I enjoyed reading your "Principle of Inclusion" and its explanation. Just a couple of days ago, I had a talk with a C Programmer who displayed his dislike of Perl. When I asked 'Why?', he replied, "Because it's a programming language made to be very loose and flexible and therefore very vulnerable."
I then explained the TMTOWTDI viewpoint and itsflexiblity in hopes that was the reason why he called Perl "loose". He eventually saw the light and realized that its based solely on the programmer's skills and experience. Lastly, he decided to give Perl another try and actually READ books and manuals this time around.
