I think that it is “not quite fair,” shall we very-agreeably say, to criticize a language for not being what it isn’t, when what it is is so darned important for so many people. When a language has been around for as long as Perl has, 100% compatibility with existing code-bases frankly becomes more important than most other considerations. This is what pays the freight. The true “warts” of a language, I think, fall out of favor on their own stink.
Now, in the course of a work-week I do find myself shifting between languages like shifting between hats. But Perl remains for me a known quantity: it is a beefy power-tool that won’t let me down. It is very hard to earn a positive reputation if you are a programming language ... let alone keep it for however-many years running. The many teams who have worked on Perl (and who have built notable CPAN packages) richly deserve full acknowledgment for their masterpiece. Warts and all.
And I am sure that I will one day say the same thing about Perl-6 ... warts and all.
