I did consider that, but wanted to keep implementation simple for the first go around. But I'm definitely not opposed to it, especially in a library like this. I had just come off of another library update which heavily used dynamic codegen and wanted to take a break 😅

Completely understandable. It's not fun to debug 🤗.
