> Now put the url fetch code into a larger application. With exceptions this is pretty easy - you can catch any exception thrown by your url fetch code and then retry it a few times until it succeeds, or you inform the user of the app. Without exceptions this is tougher as you need to unroll everything manually in order to retry. Unless you have something like goroutines - or Erlang-style processes - and perhaps employ a moderately disciplined coding style. Retrying those is just a matter of relaunching them, isn't it? Also, Common Lisp got exceptions mostly right. Many other languages...not so much, I guess.
