Maybe, the alternative perl, "Perlb"? I'd also agree with the "perpetual playground" comment, and note that Perl6 originated not as something needed, but as a way to keep the developer band together.
Plus, I've always noticed a tendency in Perl in the last few years to be interesting/entertaining... sort of like it was designed by science fiction writers.
If we're talking about the world having moved on to either Haskell, Erlang or Go, Rust, well, I don't really see that being as pervasive as it often appears on trend-seeking sites like this.
And I really hope we're not talking about JavaScript…
