Erik Naggum's Perl Rant

Hopefully now that we live in the world of the future we can use him as an example of how not to write mailing list posts.
(There were one or two angry Europeans on the ffmpeg list who got things done, but the behavior and getting things done were both seemingly caused by having lots of free time since they were unemployable…)
For what it's worth, I can do the exercises from SICP ( https://mitpress.mit.edu/sicp/ ) without much difficulty in modern Perl.
For the time being, Higher Order Perl might satisfy you ( http://hop.perl.plover.com/book/ ). It's only 9 years old now, so it's relatively modern.
This is not a good rant. It's just a bunch of disparaging assertions.
Having no clue who this cat is (well... was) I had to look him up to figure out if I cared about his 14 year old rant against Perl. One thing about him that stuck with me after reading was that he did that on purpose because it was easier to type. But that doesn't really make it better.
