Last year, we had a failed experiment with an active steering system. Instead of deleting the code, we just commented it out. This year, we began programming the robot using last year's code as a base. To clean up the code, I removed the commented out code and added a little gravestone
Also, in the last week I made a program that would use the optical sensor to find the center of the goal so that the robot could automatically grab it with our sickle. However, due to time constraints and the fact that no one wanted to add the (small) extra weight of the sensor, it was never used (or even tested!). But, being proud of the untested work, I kept it in the code, commented, with a little ascii I.V. fluid package keeping it alive.
