@nprofile1q... For fun I tried writing rust code with claude code. The code took an age to compile when it worked (do we call it build?). The project took months and so the code got large & was slow to build. Claude was able to refactor it (after it worked) to build 10 times faster. That is not mechanical as you mention... but was really challenging. Mechanical refactors it does 100 times better still of course, because it seds too yes, but it can check the new syntax & test build each change.
