  terminological questions.

  The PRL usually refers to the value of an object's __init__
  attribute as a "method".

  A method is a function that can be associated with a object
  in a special way.

  When a function is retrieved from the attribute of an instance,
  an instance method object is created (PRL 3.11.1 3.2)
  and becomes the value of the expression for the attribute.
  This usually applies to "__init__". Methods are based on functions.
  The method's __func__ attribute is the original function. 
  The instance is the method's __self__ attribute.

  But when you look at values of __init__, you can find all
  kinds of things, like "wrappers":

|>>> object.__init__
|<slot wrapper '__init__' of 'object' objects>

|>>> object().__init__
|<method-wrapper '__init__' of object object at 0x0...>
