Actually less possible since 1.9 doesn't keep around the parse tree's, 
but still quite do-able.

ex (ri_for gem):

go.rb:

 class A
    def go
       33
    end
 end
 require 'rubygems'
 require 'ri_for'
 A.ri_for :go

$ gem install ri_for
$ ruby go.rb

C:\dev\ruby\scene-skipper>ruby go.rb
 at go.rb:2
sig: A#go arity 0
    def go
       33
    end
Original code signature: def go
#parameters signature: go( [] )

Enjoy.
