Method locator and ancestral heritage

method_locator.rb

require 'method_locator'

class A
  def moo
    "A"
  end
end

class B < A
  def moo
    "B"
  end
end

b = B.new

methods = b.methods_for(:moo).map do |method|
  [method.owner, method.bind(b)]
end

methods = Hash[methods]

# Now ain’t this cool?
p methods[A].call
p methods[B].call

Might be worth noting this code uses the method_locator gem: https://github.com/ryanlecompte/method_locator
