There is nothing stopping a resurgence of Perl, if it's an order of magnitude better than competitors. If the combination of modern Perl techniques and the language make it a good enough fit for a new interesting framework or tool, then we might all be writing Perl again in a few years.
Just needs to get more jobs posted for it first. Going back to the original comment:
>What would you build in Perl today that you wouldn't build in another language instead?
You could turn it around too: what could you build in another language that you couldn't build in Perl? Well, nothing really. It's a matter of taste, and I think what continues to set Perl apart is its syntax, which could be really good and readable when you don't try to do code golf.
I didn't say could or couldn't, we're talking about turing equivalent languages of course so that question is meaningless, I said would. You can code anything you want in native assembly, or in brainfuck even. But why would you? If you have some impressionable new college grad just getting into the industry how would you convince them to use Perl to build things instead of any other option?
