With a certain amount of work and hooking of Module::method_added,
Module::included, and Class::inherited you could probably get the
information you want. The base system, however, does not track that
information. Your hooks would have to gather the info and make it available
through some API, such as what you suggested. Also, if some piece of code
was a poor citizen and overrode one or more of your hooks without making
sure to call it (either with an alias chain or with super), you're out of
luck.
