“Cosell: I have to admit that I did both. I would make things simple in the large. But when I say that programs should be easy, it's not necessarily the case that specific pieces of the functionality of the program have to be easy. I could write some very complicated code to do the right thing, right there, code that people would cringe at and not be willing to touch. But it was always in an encapsulated place. Most of the bad programs I ran into, the ones where I threw things out and recoded them, there wasn't a little island of complexity you could try to understand and fix, but the complexity had oozed through the program.”
