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.

 * The reason for Parrot, part 2 explains closures.

 * Continuations and VMs explains continuations.

 * Continuations and VMs, part 2 rounds things off by explaining why the JVM
and the CLR are unsuitable environments for supporting these language

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 ;-)
