Appendix showing non-obvious invocations for magic methods

[RafeKettler]

http://www.reddit.com/r/Python/comments/fb4xz/guide_to_pythons_magic_methods_work_in_progress/c1enahq suggests a table for non-obvious magic method usages, e.g. __iter__ is invoked by for x in container, etc. I'd like to add it as an appendix or something similar.
