ReverseEng an Object's methods?

[Mark T]

Could there (ever) be a way to reverse engineer, (to code), an object's methods?
In the case where the object/module has been extended?
Is this more possible with 1.9.n?

You can use ParseTree and ruby2ruby in 1.8 (only).

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.
