You'd say it makes "commit" no longer a static variable, passing it around instead. Next I ask you why. The answer would presumably be something like "because ... static variables are bad", or "because passing it around explicitly makes it easier for a person reading the code to see how the state evolves", or "because some day we will want this to be thread-safe, meaning there could be more than one commit being cherry-picked at the same time". Right?
