The problem with ++ is not understanding what it does. It's remembering exactly how to use it appropriately in the given context, and never making a mistake. And, the affect is multiplied by C's semantics, specifically, given that off-by-one pointer shenanigans can lead to Very Bad Things. So, tricky to use thing that blows up big when it does blow up.

To make an analogy, I can perfectly understand null and what it does. My objection to null as a language feature is not based on not understanding it and what it does.
