isn't a bad quick explanation, provided you don't mind a little scheme code.

The Coro::Cont module is sort-of close to a real continuation, although the 
way it implements it isn't really right and as such you can only re-invoke the 
continuation once (which takes away most of the fun :)

There's also some ancient code of mine at

http://dev.catalyst.perl.org/trac/bast/browser/trunk/historical/rev1/r2

which illustrates using continuations in Inline::Guile code to allow you to 
write (apparently) synchronous code which then runs asynchronously on top of a 
POE kernel.
