require 'delegate'

class Foo
  def me
    puts "meee"
  end
end

foo = Foo.new
delegator = SimpleDelegator.new(foo)
m = delegator.method(:me)
p m
delegator.__setobj__([1,2,3])
m.call

# MRI: Note inspect says the method is defined on SimpleDelegator.
# #<Method: SimpleDelegator#me>
# trust.rb:14:in `call': undefined method `me' for [1, 2, 3]:SimpleDelegator (NoMethodError)
# 	from trust.rb:14:in `<main>'


# I can achieve the same looking #inspect in rbx with:
#
# cm = Rubinius.find_method(foo, :me)
# Method.new(delegator, cm[1], cm[0], :me) <-- Note receiver argument.
#
# However the call is still made to the compiled method, m[0].
