## Wrapping integers in Python with Metaclassing

I often require a wrapping integer type in Python, by which I actually mean a subclass of int where all operations are performed modulo some constant number $N$. There are two main use cases for this: 1. Working in a finite field for some cryptographic stuff, or solving problems on [Project Euler](https://projecteuler.net/about). 2. Having Python integers behave like machine registers (8, 16, 32, 64, even 128 bits - you name it.) I decided to solve this once and for all and wrote the integer wrapper class to end all integer wrapper classes. I also managed to keep it rather compact by using *»gasp«* metaclassing. Do you want to know more?
