-It's bound to happen: something you thought was a good idea didn't work the way you planned and now you realize you've made a terrible error. Sometimes it's something that could have been easily avoided (committing code that was meant for debugging, for instance). Sometimes it's a cascade of errors, each building on the efforts on the previous error. There's the mistake of neglecting the side-effects of a module when it's used in a way that wasn't intended, or it's the realization that you've designed a small, tightly coupled module only to learn that your module will be part of a larger piece of software and your code isn't designed to make a smooth transition. Whoops!
