class Module
  # Works like <tt>attr_accessor</tt> but generates private getter/setter
  # methods for class internal use only. Useful for enforcing Smalltalk-style
  # internal encapsulation.
  #
  # For a more complete implementation of a similar feature see {ivar_encapsulation}[https://github.com/citizen428/ivar_encapsulation].
