             By default, a newer autoreload algorithm that diffs the module's source code
             with the previous version and only reloads changed parts is applied for modes
             2 and below. To use the original algorithm, add the `-` suffix to the mode,
             e.g. '%autoreload 2-', or pass in --full.
