I wonder how much his opinion would change if he used a modern version of Perl... note that his docs on the Range operator read:

Be aware that under the current implementation, a temporary array is created, so you'll burn a lot of memory if you write something like this: ...

That how it was in perl5.004. In 5.005, which came out over 8 years ago, this was fixed and the docs were changed to read: 'In the current implementation, no temporary array is created when the range operator is used as the expression in "foreach"'.

There have been what... about twenty-some releases since then? No wonder he's confused and thinks the language is dead...

One point in his defense though: he does say, "use Ruby". Personally, I think Perl6 should be abandoned and Ruby should be adopted as Perl7.
