The preferred spelling for:

    platform.__builtins__.__class__ 

would be

    type(platform.__builtins__)

It's shorter and easier to read, but essentially says the same thing.

You can also use it on integer literals, which you can't do with your
syntax:

    >>> type(1)
    <type 'int'>
    >>> 1.__class__
    ...
    SyntaxError: invalid syntax

Admittedly, this is a trivial benefit.  If you're using a literal, you
already know what type you're dealing with.

Cheers,
Cliff
