Docstrings and comments are amazing to be able to work with huge code bases with big teams where you don't want to understand the whole code base, because it's impossible.

If the goal is to not abstract anything away, and always look at the implementation itself to be able to change it / rewrite it, keep it tiny and it is able to beat PyTorch+CUDA+LLVM with 1000x smaller codebase, who am I to judge?
