I could! I'd probably have to take it piece by piece, rather than telling an AI to edit hundreds of files in one epic session and hoping for the best. Even just reviewing a commit that large feels like it would be a bad use of time. Also, giving every variable a type (or using "mixed" everywhere), and giving every function a return type (more "mixed" or "void") would just make the code more verbose without any justification that I can see.
With Zed, I feel like I'm being dragged into a modern style guide that I never agreed to. It would be nicer if I could make it my own by turning off those parts that I disagree with and keeping the rest. I know this is technically possible, but they've certainly not made it easy.
