There is not. The closest you can get is a hack that reads in source
files (if you know where they are, and they're pure Ruby) and either
parses the raw code or looks at the abstract syntax tree.

Though I'm not actually recommending that you use it, this is why I
wrote my own DescribeMethods module:

(Seriously way more work than you want to do, I'm sure.)
