"Code Complete" recommend AGAINST end comment

Section Commenting Techniques:

Aside from a couple of special cases, endline comments have
conceptual problems and tend to be used for code that's too
complicated. They are also difficult to format and maintain.
Overall, they're best avoided

You don't need to use the technique [endline comment] for
short loops that aren't nested

When the nesting is deep or the loops are long, however, the
technique pays off ... [but] the best way is often to rewrite
the complicated code that requires tedious documentation.

 Deep nested loops can (and should) be avoided.

Section Taming Dangerously Deep Nesting
Section Controlling the Loops, How Long Should a Loop Be ?

* Make your loop short enough to view all at once
* Limit nesting to three levels
* Make long loops especially clear
