Never heard of them. What do they do?

tl;dr write maintainable code and don't prematurely optimize.

The real cleverness lies in being able to write code that seems self evident in hindsight. Anybody can write convoluted code that's impossible read after, but it's a lot harder to express the problem using simple and clear code. The ability to understand a complex problem then express it using clean and maintainable code is what separates junior developers from senior ones.
