" As of 2009[dated info], multiple Perl 6 implementations are under development, but none of them are considered "complete". "
So, there have been releases of Perl 6 but no finalization, but aren't most programming languages like that now?
e.g. C# has 6 versions and Java (12ish, according to Wiki). Languages forever evolving.
I know PERL is old and people except it to be more rigid like Fortran (even with new versions), but Fortran isn't being used for web apps, etc. that see constant technological innovation.
