And FTR I still disagree, strongly, that Perl 6 hurt Perl 5 particularly or in the grand scheme. Perl 5 was circling the drain *beforehand*. That was the entire genesis.
At the time it seemed like we were being sold a new car just to fix a flat tire. I'm not faulting a language designer for preferring to design languages than to maintain and evolve them. Imagine if all the energy that went into apocalyptic criticism of Perl 5 was instead a rewrite (or mere tweaks) of mod_perl and a few more core modules so it could meet the competitive challenges.
