module Decorate
  def decorate(definition, options)	
		self.send(:alias_method, "__original_#{definition}", definition)

Memoize memoizes function return values based on class name, method name, and arguments. This means that this only works for functions that use state / have side effects.

module Memoize
  def memoize(definition)	
    self.send(:alias_method, "__original_#{definition}", definition)

    define_method definition, Proc.new { |*args|
 @__memo ||= {}
