It's absolutely worth it. Stopping execution flow at erroneous or ambiguous statements is an essential part of secure, reliable programming. A notice or warning offers no protection at all. Unless you've taken some very specific steps, your program will continue operating as if they never happened, even if that notice or warning was clearly a high probability of being a bug.

People should not have to opt in to common sense defaults. If I sell you a car, you shouldn't have to opt in to having the bolts on your tyres fastened on tight enough that the wheels don't fall off the moment you hit motorway speed.

Let's not. Never again should an option like enable_short_tags exist. If you want a per-file opt out, the notion of declare(sloppy=1); Has already been jokingly proposed, and I would personally have no problem with it if people want to opt-in to less reliable enforcement... but once again, I stress that the defaults should always be best-practices. -- Mark Randall
