Continuing the TSSJS venue

Ive just been relaxing in the back on a session with Geert Bevin, the founder of the RIFE framework and he has been explaining to us about continuations and how it is beeing used in RIFE, a webframework that uses continuations heavily.
I was missing some informations related to how continuations may be used decoupled from RIFE by apart from that it is a very powerfult concept. I am not really sure how it will affect the programming model that I am currently using on my projects since all the classes that may contain state in continuations must be cloneable, but I will have to dig into that.
