We just had a big error in a piece of code. The error was because we had this:

   if sys.errno:
        my_favorite_files.append(sys.errno)

        my_favorite_files.append(sys.errno)

The aggressive casting anything to Boolean because it makes if statements easier is something that I would not expect to find in a language that is type-safe.
