Iterators and inside-out objects: Perl closures at work

Abstract

Closures are a powerful abstraction common to modern dynamic languages.
They're functions that maintain information between calls, and can in
some ways be thought of as objects.

In this gentle introduction to this advanced concept, you'll learn how
Perl's lexical variable scoping allows closures, and how to apply them.
We'll discuss:

* Iterators that allow walking through a sequence of data or actions by
maintaining state between calls.

* "Inside-out objects", a method of creating objects in Perl that is
gaining in popularity. 


(Later today, I'll send out official info about Mark-Jason Dominus on
Feburary 6th)

xoxo,
Andy
