Hey, could you also add in Perl6?
Perl6 is sufficiently different from Perl5 as Perl6 drops the previous reverse compatibility to Perls 0 through 5 in its functionality. With that compatibility being removed with the simple line, "use v6;". It was figured that compatibility to previous Perls such as the ones that were terrible ideas Perl 4 and Perl 0 was making the language much harder to manage and keep track of it. Much of the updates and moving forward with Perl 6 has been via a washcycle way of handling stuff (as compared to the waterfall style)
Possible cons for Perl 6 is that the bicycle shed is the exact wrong colour. I don't know if they are trying to attract robots and kittens with that colour of the bicycle shed... but seriously... how do they handle that bicycle shed being that darn colour?
I kind of was thinking Perl 6 was already an option... and tend to be disappointed for the one hundredth time I don't see it up.
I'd also suggest we offer Perl 0... but Larry Wall does not seem willing to make Perl 0 available to the general public and world. Clearly he is hiding it, because it is the secret to enlightenment and godhood--and he doesn't want other gods to compete with him.
