Python 3000 took eight and a half years from conception to its 3.0 release, and its changes were relatively minor
In a google tech talk, Guido specifically mentions that he doesn't want Python 3000 to go the Perl 6 way and the Perl 5 people just don't give a damn about it anymore!! Well thats the reputation Perl 6 has in the Open source community, It has just become an example of what not to do!!
