I think OP just found a really well done C file. You can definitely see many famous projects on GitHub, where even though the code is logical, you can't help feel it's a bit all over the place. cpython isn't all sun and roses. A broad generalization, but with C and C++ I'd say the standards for "good code" have dramatically risen in the last 10 years. Variable names seem to have doubled in size.
