[LRUG] Continuations (was Re: The first LRUG Code Review needs your ruby!)

[Chris Parsons]

Thanks - I thought this continuations stuff was pretty interesting.

Struck me that some sort of journaling of object changes might be a  
good way of rewinding to previous states arbitrarily. You'd have to  
redefine some pretty low-level stuff, but then once it's done the  
higher level code gets much simpler:

Object.checkpoint(:some_point)
# do stuff
Object.rewind_to(:some_point)

Needs refining to make it work across the whole program state ... any  
ideas?
