Subject: Inspetting a method's caller

Hello.
How can i know a function's caller method? E.g.

class A
  def do_stg(n)
    b = B.new
    b.do_xyz(n)
  end
end

class B
  def do_xyz(n)
    # -> Here i want to know that
    # -> This method has been called
    # -> From A#do_stg
    n + 1
  end
end

Kernel#caller does not help.. i don't care what file or line a function
has been called, and i couldn't find nothing helpful on ruby-doc nor by
searching google :|
Please keep in mind i'd like to know that do_xyz has been called by
do_stg -> WHICH IS A METHOD OF THE "A" CLASS <-

Thanks for your help :)
