It complicates the code, and pollutes the name space a little bit.
More importantly, it's an option that a new program will be forced
to spend time trying to understand and avoid.  Until it's shown
to be helpful, I would like to not even have to consider it.
(If you like, leave a comment behind in the code, as a reminder.)

It's like seeing forty five types of green salad on a restaurant
menu, when the hungry masses all like the same one.
