I might have if Perl had a history of doing so. But Perl 2 was backwards compatible with Perl 1. And Perl 3 was backwards compatible with Perl 2. And Perl 4 was backwards compatible with Perl 3. And Perl 5 was backwards compatible with Perl 4.

In your terminology, that would mean that Perl 2 was the next Perl 1, Perl 3 was the next Perl 2, Perl 4 was the next Perl 3, and Perl 5 was the next Perl 1. Hence, Perl 5 is the next-next-next-next Perl 1.

And then Perl 6 isn't the next-next-next-next-next Perl 1.
