I personally don't find an irony. Perl may not be the most popular language ever, but it definitely has its place. I do find an irony that the 0.1 specification of Perl is worst than the 0.1 specification of Dart.
Why is it surprising that a language designed to occupy a niche between shell and C in 1987 had a spec faster and looser than a language designed from (let's say) 2009 through 2011, based on an existing, popular, and well-understood language with well-publicized flaws?
Sure, but is it? Does it have any chance at all of being "the language of the future"? Or, is it a very old, mature language that has reached a plateau or is in slow decline?
