As is often the case with refactoring, the early stages were mostly driven by trying to understand what was going on. A common sequence is: Read the code, gain some insight, and use refactoring to move that insight from your head back into the code. The clearer code then makes it easier to understand it, leading to deeper insights and a beneficial positive feedback loop. There are still some improvements I could make, but I feel I’ve done enough to pass my test of leaving the code significantly better than how I found it.
