class_docstr: A non-data descriptor that makes a value only visible on the class.
  
  This is like the "classmethod" builtin, but does not show up on
  instances of the class.  It may be used as a decorator.
code: def __init__(self, value):
      self.value = value
      self.getter = classmethod(value).__get__
      self.name = None
