The Open-Close Principle Is Good for Programming

A lot of programming, the sort of oral history comes from the problems of language designers. And so a big problem for me isn't creating a reusable standard library that is easy to use correctly and hard to use incorrectly. I certainly wouldn't make the claim that code that follows the open code principle is just always better than code that does not. It's an emergent property of the code and the way you're going but very rarely do you sit out and go, I'm definitely going to reuse this.
