Ummm, so, the suggestion is for me to take proprietary code from work, and
post it on the internet. I'm not sure that would go over so well.

Everyone's opinion aside, I've been using this style in my code, and find it
completely unobtrusive. It makes the code more clear at no cost. People
start using the libraries I write, and the use of my libraries is clear
throughout the code. As time goes on, and we move into our next project,
I'll use the idea throughout, and it will make maintenance easier in the
long run. I only brought it here because I've found it useful myself, and
thought others might as well. Now, I know some people are interested. I
know that this will be used where I work, although I can't say to what
degree yet. I know other programmers outside of work who think it's a good
idea, and may end up using it.
