I think you're projecting. The point being made was that when you're writing a simple stack (as you often might do in C, since the standard library and the language itself conspire against providing you one) and you don't have the overhead to write multiple functions to wrap it up (vertical space is an issue when you make more than one of these–trust me, I used to write Java and every thing about it was just a papercut in verbosity), the post- and pre-increment versions are concise, idiomatic, and–to be honest–more clear simply because they use the operators in the way that they are meant to be used. I can glance at them and see, OK, this one gives me whatever the stack is pointing to and then makes it point to the next element; this one first moves the pointer to the next element (which is free) and sets it. All in one line. There's nothing to show off here, this is just how you write C; those operators exist for exactly this purpose (and IMO single letter variable names are generally only a good idea in the smallest of scopes, and I personally use braces even when optional).
