summary
Lists the actual Ruby hooks covered, shows method_missing with the proper signature and why also to implement respond_to_missing, demos new implemented roughly in Ruby vs C, warns against const_missing and recommends require/autoload instead, demonstrates module lifecycle hooks (included, prepended, inherited) and singleton-method hooks, explains implicit conversions and a working coerce example for numeric-like types, and proves at_exit blocks run in reverse registration order and how to check for exceptions.
