fwiw, I concur 1000% with all the above.
(Update: Except for the bit about turning CPAN into junk. Failing to utilize it isn't the same as turning it into junk. As has been pointed out many times, P5 will continue to exist for a long time.)
I for one agree that the name should have been changed. The new language is a spiritual heir of Perl, but it's different enough to warrant a new name. Oberon was far more similar to Modula than P6 is to P5; Modula was also yet more similar to Pascal. You might argue that those represent a negative model, being, as they were, somewhat losers in the language race. I submit that they would have fared no better had they been named Pascal 7 and Pascal 9.:-)
