Only 82 more minor releases until Perl 6 will be available.

Almost ;-) The current perl version is 5.018000, so that would take 982 releases until the numbering scheme breaks down. Of course, Perl v-strings can have elements of INT_MAX each, but I doubt such high numbers would ever be used, for back-compat reasons.

Perl 5 will not ever go to Perl 6. Although you probably forgot the sarcasm tag. :)
