For clarity: Perl6 does suffer from the same implementation problems as Java and always will. Nevertheless ...
In my post I didn't use the word "always" because who knows what will happen? Maybe in 5 years Rakudo will be abandoned and the standard Perl6 implementation will be quite different. But I've seen nothing to suggest that, looking from the outside.
AFAICS, Perl and Perl6 will always have orthogonal use cases. It's only the Perl6 name which will damage Perl's usage and that is a real shame.
Update Oct 2019: I'm pleased to say that there is finally a new name for this language (Raku) which we can all hope will go some way to mitigating the damage already done to Perl and ensure that no more is done in future.
