These are somewhat true but irrelevant statements. No one has used perl 4 since the early 90s. There's no Perl 6, only Raku. And I'm thankful for Raku mess diverting and then driving away developers that wanted change, it meant Perl didn't become the popular mess the pythons have.

For my entire life Perl 5 has been Perl and Perl code just works no matter when the OS system Perl is from. This is the pragmatic reality: it just works. And that's an amazing property for system administration and software distribution.
