The problem is, in my experience the coders won't find the obvious, easier, cleaner or efficient (in any mystical meaning of the word) way but that one *they* understand. I work with some people who aren't that much into Perl as I am, and they use only those syntactic sugars of Perl which they know from PHP. Maybe they find it more readable, but you should see what some people produce when trying to avoid using map, grep and such alike :)
