Although I'm familiar with this practice I really don't care for it much. Admittedly, it's just a personal preference. I don't think it flows as well when reading it though. More importantly, there simply is no substitute for learning to be cautious. This trick works nicely when one of the operands is a constant but not at all when they are both variables.
