Re: [SC-L] How can we stop the spreading insecure codingexamplesattraining classes, etc.?
Also, exceptions (unlike gotos) cannot be used to jump backward, thereby creating hidden loops. Used correctly, exceptions eliminate large amounts of code that would otherwise be required to handle unexpected failures at every level in a function call stack and propagate such failures upwards by way of return codes etc. to a point at which some remedial action can be taken. Exceptions can certainly be misused, but they are much better than the alternatives in many situations. David Crocker, Escher Technologies Ltd.

Re: [SC-L] How can we stop the spreading insecure codingexamplesattraining classes, etc.?
I take exception (haha!) at having them dismissed like this. It sounds like you encountered some badly written exception handling code. Error handling can also be really bad, where at every call layer the original error gets filtered or translated to a point where you just know something went wrong somewhere but have little idea what. Then you have to trace (yuck) and waste hours trying to identify the problem. I'll take limited state over no state any day (Ruby even tells you which line numbers of which files were involved).
