Method deprecation helper

gistfile1.rb

module MethodDeprecator
  def self.included(base)
    base.extend(ClassMethods)
  end
  
  module ClassMethods
    def deprecate_method(method, replacement)
      class_eval <<-DEPRECATE_METHOD_END
        def #{method.to_s}_with_deprecation
          puts "WARNING: Deprecated method #{self.class}##{method.to_s} called, use #{replacement} instead.  Called from #{Kernel.caller[0]}"
          #{method.to_s}_without_deprecation
        end
        alias_method_chain :#{method.to_s}, :deprecation
      DEPRECATE_METHOD_END
    end
  end
end

Kernel.caller is the whole execution stack, isn't it? So you can use Kernel.caller[1] instead to get one level up.
