As a counter to Chesterton's Fence: sometimes the fastest way to understand what something does is to remove it and see what complains. You might get only 1 complainer for every 10 fences you take down. Putting that one fence back up takes much longer than taking it down, but the time saved from removing the other 9 unnecessary ones makes it a net win. And this time you can add Documentation to the rebuilt fence.
