Can't agree with this one enough. I'm currently battling through a project full of people that are too smart for their own good and too stupid to realise it.

I had a huge argument today with someone that wanted to wrap a certain type of higher order function ("foos") in another higher order function with a particular name ("fooGenerator()") for the sole purpose of differentiating it from a different kind of higher order function in the same file ("bars").

I lost the argument. It turns out using heading comments to seperate groups of similar functions, or god forbid splitting up the 400 line file into multiple smaller ones, is too confusing and prone to errors by maintainers ("What if they put a new foo function in the section for bar functions!")
