This honestly sounds extremely limiting. I do get why you'd want to make functions short in general but I think there's a tipping point where making the functions shorter actually increases overall complexity and 4 lines seems to be past that tipping point in my experience.

It's honestly not as limiting as you might think. Readability has definitely improved a ton since switching.

Of course we don't count every bracket or blank lines. Only the rows with any logic or assignment.

And yes, I agree, there are occasions where the complexity goes up. If there is a good argument for that, then we of course go with it.

But so far, almost everything anyone in our team has made, has been improved by rewriting it to something that works well in 4 lines, be it using polymorphism, object oriented, or functional.
