I would add a couple more things:

1. Use an editor that can find the opposite brace. I use EditPlus (www.editplus.com) and I can press ctrl-] to find the other side of a code block.

2. Usually (there are always exceptions) if your code block spans more than one screen vertically it could be broken up into functions to make it easier to read, and to promote code re-use.

As for the approach of placing the punctuation of the code block first, that is something I have only this year started doing and it is a huge help.

Thanks for a nice article.
