I don't know what you're implying - I asked a genuine question: what is impressive about that syntax.
It's not the syntax that's impressive. It's that most people who don't know C, likely wouldn't consider array access to be commutative.
They never said it was impressive. Just that they like to demonstrate it, presumably to people who don't know about it.
