in reply to Class/Object Method Lister
What you describe is precisely what I was looking for myself, a while ago. When multiple levels of inheritance exist, it is terribly hard to figure-out what you can do with an object...
With your small script, you can figure-out what functionality is available... but you still have to go through the manual pages to figure-out the exact meaning of the methods found. IMO it is mostly solving a documenting problem.
Therefore, I have create a documentation tool which helps you with that. Have a look at the OODoc documentation to see how this cross-reference looks like... and it is only a small extension to POD which produced those pages (both in POD and optimized HTML).
