You may wish as hard as you like, but wishing will not change reality. The reality is that set -e is worse than useless rubbish. It is deceptive. It is a trap for the unwary. It makes you THINK you're using some sophisticated advanced scripting language with exception handling, but you are NOT. You are using a horrible duct-tape hack from the mid-1970s. The sooner you acknowledge that set -e is NOT intended for use in new scripts, but instead is ONLY provided to make those old mid-1970s scripts continue to "run" the same way today as they did back then, the better off you will be.
