Why is Perl missing from coursera... (Score 1)

I can find dozens of courses on Coursera where Ruby/Python/Javascript are used as the programming language for courses related to Data Science, Machine learning, web development or just basic programming. But not a single course based on either Perl5 or Perl6 is available on the various MOOC sites. Do you see any potential for Perl5/6 to be the language of choice for teaching any technical concept? Any examples where Perl is breaking new ground?
