Yeaahh.... What did you expect?  ;-)

That would be a very good idea indeed. I have been wandering around for 
some time with the same and slowly started to add comprehensive (?) 
comments to those macros or includes I use most often as I generally 
forget what or why to do in particular cases from one project to the 
other. Re-inventing the wheel each time as it were...

Your example looks very neat. I shall study it some more and take 
inspiration from it.

Not that I mind to re-ignite the discussion every few years as I seem to 
do ;-) but I fully agree with you on this.
