New submission from Роман Донченко <DXDragon@yandex.ru>: The language reference says this in section 3.2: ~ Built-in functions A built-in function object is a wrapper around a C function. Examples of built-in functions are len() and math.sin() <...> Special read-only attributes: <...> __self__ is set to None (but see the next item) <...>. ~ That is not the case: ActivePython 3.2.2.3 (ActiveState Software Inc.) based on Python 3.2.2 (default, Sep 8 2011, 10:55:13) [MSC v.1500 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information.
len.__self__ <module 'builtins' (built-in)> open.__self__ <module 'io' (built-in)> import math math.sin.__self__ <module 'math' (built-in)>
