" Thanks to Dan Sugalski (designer of Parrot, the next generation Perl VM) I finally understand what continuations and closures actually are. He explains them as part of a comparison between the forthcoming Parrot and two popular virtual machines already in existence:

• (Perl|python|Ruby) on (.NET|JVM) leads in to the explanation. http://www.sidhe.org/~dan/blog/archives/000151.html

• The reason for Parrot, part 2 explains closures. http://www.sidhe.org/~dan/blog/archives/000152.html

• Continuations and VMs explains continuations. http://www.sidhe.org/~dan/blog/archives/000156.html

• Continuations and VMs, part 2 rounds things off by explaining why the JVM and the CLR are unsuitable environments for supporting these language features. http://www.sidhe.org/~dan/blog/archives/000157.html "

ka ps. In order to focus on Python promotion and site-redesign efforts I've suspended delivery of python-dev email in the short-term and will only be scanning the archives as time permits. If you need to flame me, please address your emails to me directly or /dev/null, your choice ;-)
