If you're writing programs not poetry (I do appreciate both!), you want continuation operators when you grab control at unpredictable points (e.g., timer events) or when you compose functions and the continuation is difficult or impossible to compute (e.g., if you used +/- many times). 

Am I naive to think of this use of delimited continuations as basically being a version of 'yield' with external control over the yield boundary?
