For when nothing else will to place a warning, in your code, to your future self or your fellow developers paste this:

//
//  NOTE           NOTE           NOTE           NOTE NOTE NOTE      NOTE NOTE NOTE
//  NOTE NOTE      NOTE      NOTE NOTE NOTE           NOTE           NOTE
//  NOTE NOTE NOTE NOTE      NOTE      NOTE           NOTE           NOTE NOTE
//  NOTE      NOTE NOTE      NOTE NOTE NOTE           NOTE           NOTE
//  NOTE           NOTE           NOTE                NOTE           NOTE NOTE NOTE
//

It looks like hell here but trust me - after you copy/paste it into your editor, it will look something like this:

Lovely. I wonder if I'll heed it when I see it.
