Fool.

Fool (less so, though).

It was obvious¹ I was talking in context of my example. I used "no
indentation" because in that case "no indentation" was correct. If you
indent line #1, it follows that other lines might well be indented to
keep style consistent.
¹ I hope. I never suggested otherwise.
Since it's not too clear for you, my usage of fool was meant
pseudoironically as a subtle reminder that it's all subjective anyway,
but that I'm also still right.
