It's not at all an attempt to discuss Perl 6, I wouldn't presume to second guess the developers on that topic. It's really just an exposition of the more fundamental ideas of programming languages in general, particularly lexical closures and continuations, and the interesting places you can get to if you follow those leads. Really just a jumping off point for people who might like to explore further.

I must stress that this is not a book about perl, it just happens to use perl because it is a convenient language and has a wide user base (and because I like Perl.)

perl -e 'print sub { "Hello @{[shift->()]}!\n" }->(sub{"World"})'
