I see two possibilities:
you either
 * access the method repeatedly using the symbol: in that case you can
 store the information in a hash somewhere (say a hash in the singleton
 class of the object), using the method name as the key
 * keep the Method or UnboundMethod (if using instance_method) objects
   around; then you can add that info to the object itself directly,
   using its instance vars + singleton methods.

Per-method annotations as shown in 
http://www.onjava.com/pub/a/onjava/2004/04/21/declarative.html
can be implemented trivially using Module#method_added (it's the same
technique used commonly to implement docstrings).
