You said the simplest syntax trips people up, but I totally disagree. The real problem is almost never the syntax itself. It's that people jump into writing code before they even know what the loop should do. They don't think it through on paper first. So they stare at the screen trying to fix the wrong thing. The syntax error is just a side effect of a bigger planning mistake. That's why the paper trick works, it forces you to solve the actual logic.

Ugh, it's in everything now.

But do you ever worry that skill is just dying out for most people?
