Method introspection question

Hello

Is there anyway to get back the definition of a method within a running
program [or irb session]?

For example, if I declare a method:

def hello
puts "Hello"
end


is there anything like hello.source to get back hello's code?

Thanks.

If you implement an solution, please contact me via private email, thus
I can update the document.

This way evaluators (or users) can immediately detect (and use) the
functionality.
