What about for beginners like me who instantly understood `++` and `--` as increment&#x2F;decrement but avoided `+=` and `-=` for being rather nonsensical?<p>This half-reeks of something that a professional&#x2F;advanced user <i>thinks</i> trips up beginners without <i>actually tripping up beginners</i>. Or they have an anecdotal sample size of n &lt; 10 and decided since it confused 1 person that 10% of people get confused.
