This makes me think: many generic data structures don’t actually require type-specific code and only need to be generic over data size (unless dealing with non-trivial types). Typical C++ or Rust's monomorphic implementation creates a lot of redundant code.

I hadn’t used my Windows machine in a while, and when I came back to it, I noticed that `git status` had become very slow. After some digging, I found that `git status` spends a huge amount of time on the submodule operation. I am still not sure whether submodule is the culprit, though. ☹️

A tale of overengineering: I implemented short-string optimization in a `StringBuffer` type. The catch? This project uses arena allocators for everything, so dangling pointers are usually not a concern. However, since the `StringBuffer` data might reside on the stack, I need to be extra careful.
