It's finally here! I've been looking forward to it for so long. Apocalypse 6: Subroutines, is finally here.
In Perl culture the term "subroutine" conveys the general notion of calling something that returns control automatically when it's done. This "something" that you're calling may go by a more specialized name such as "procedure", "function", "closure", or "method". In Perl 5, all such subroutines were declared using the keyword sub regardless of their specialty. For readability, Perl 6 will use alternate keywords to declare special subroutines, but they're still essentially the same thing underneath. Insofar as they all behave similarly, this Apocalypse will have something to say about them. (And if we also leak a few secrets about how method calls work, that will make Apocalypse 12 all the easier--presuming we don't have to un-invent anything between now and then...)
It's 41 pages!
