Note that the errors arise when the exception disrupts the sequencing of side effects. No side-effects (like state), no problems.

All right. But AFAIK only pure functional programming avoids side-effects, isn't it? ;) How reimplementing the exemple above with no side-effects (in Perl, Java, Python, C++...) is beyond me.

    Well, when you write your own code in a language like Perl or Java, you can always try to minimize and localize side-effects. That is, you can try to make most of your functions pure, reduce the need for looping by using higher order functions, doing I/O at the top levels, not willy-nilly in the bowels, etc. When it comes to libraries though, you're at the mercy of someone else. Them's the breaks.
