I always, always, always, always test my code before posting it. I think that any responsible monk should do the same, no matter how good you think you are (and I have seen other Saints post mistakes). Not testing your code might allow you to post it faster, which some see as an advantage because some days, to be honest, this place is more of a "who can answer it first" rather than "who can answer it best." Remember that higher experience indicates not only (hopefully) a good grasp of Perl, but more importantly, it indicates that someone has actual Free Time to spend on the site answering questions. Ok, I've diverged a bit. Perhaps this is the topic of another discussion. For the record, I usually reformat (there are notable exceptions*) and my guidelines are pretty much the same as japhy's above.
