So, what's new from Perl?
A few weeks ago I read a discussion thread that mentioned Perl. It might be about Mojolicious 2.0 release, on reddit, my memory is failing me. A commenter asked about what novel projects that originated from the Perl community the past several years (like the last 3 years).
Perl used to be the source of ideas that get copied to other languages, e.g. DBI, WWW::Mechanize, and its regex flavor. Now the tide has turned, and although that is not a bad thing, one might wonder the same question.
However, I believe Perl still has a lot to offer in other areas, esp text processing. There's Marpa, a new kind of parser that's written in Perl originally. There's also Regexp::Grammars, of which I haven't found equivalents in other languages.
(Also, while slightly off-topic, there are old projects that have not been properly ported to other languages. No other languages have bothered to build an infrastructure like CPAN (including RT, regression testing framework and all) for example. Last time I checked, in terms of features mod_ruby and other languages' equivalents are still lagging far behind mod_perl.)
