Continuations aren't that magical. They don't go back in time, just  
space as it were. IOW, if you can't do it with first class functions  
(possibly using CPS) (or catch/throw or exceptions (although  
exceptions for flow control is evil)), you probably can't do it with  
continuations either. Of course certain things may be easier to  
express with continuations. Continuations are really just glorified  
gotos.
