Good introduction to the space in Python (although a lot of languages have it, and just as many disallow it). I'm still on the fence regarding how useful or confusing it is. without (or even with) good variable names, "a + b" is an absolute mystery, especially when handling objects that come from classes you have no detailed internal understanding of.
I feel like it is on you to understand these classes first though. In game engine programming, operator overloading is often just vector algebra. If you have no idea how matrix-vector multiplication works, then you have no business doing those things anyway, overloaded operator or not. But if you do understand it, it makes your code infinitely more readable than without overloading. And everyone with a math education will also understand that aspect of your code, no matter if they are familiar with your usual paradigms.
