Don't start with the Lisp? |

==Don't start with Lisp==
I don't think the initial examples should be in Lisp. Here's why: the vast majority of Lisp programmer will already be familiar with closures, but a lot of people who navigate to this page will tend to be people who aren't familiar with Lisp (if they were familiar with Lisp, they'd probably know what a closure was already). I'd suggest (for the initial examples) some language which has syntax which is more C-like. Maybe javascript? Or maybe pseudocode. Of course, definitely include the Lisp code later. Just not the very first thing. Does anyone else agree?
==Closures in Perl==
In perl at least, a closure doesn't have to be a function definition. It's more or less anything between a pair of braces, that serves as it's own variable scope. In Damian Conway's ''Object Oriented Perl'', I believe he uses closures to implement the private variables of an object, so it might be misleading to say that the closure itself is an object or acts like one. In any case, something needs to be said about scope here. [[user:Wesley|Wesley]]
