New submission from Serhiy Storchaka <storchaka+cpyt...@gmail.com>:

The complex class has special methods which always raise a TypeError:

   __int__
   __float__
   __floordiv__
   __mod__
   __divmod__

After removing them the corresponding operations (converting to int and float, 
operators // and %, function divmod()) will still a TypeError.

Advantages of removing:

* Less code to maintain.
* More uniform error messages.
* Clearer output of help().
* Possibility to implement a type with __rfloordiv__, __rmod__ and __rdivmod__ 
which support complex numbers.
