Would this be possible?
=======================

.. sourcecode:: python

    class Pizza(Fields.name.size):
        pass

.. sourcecode:: pycon

    >>> Pizza("Pepperoni", "large")
    Pizza(name='Pepperoni', size='large')

-----

How about this?
===============

.. sourcecode:: python

    class Pizza(Fields.name.ingredients.crust.size):
        pass

.. sourcecode:: pycon

    >>> Pizza("Funghi", ["mushrooms", "mozarella"], "thin", "large")
    Pizza(name='Funghi', ingredients=['mushrooms', 'mozarella'],
          crust='thin', size='large')

-----

But ...
=======

.. class:: center

Before we consider this for inclusion in the standard library ...

-----

What would normal people say
============================

.. class:: center

    „Don't speak around saying that I like it.”

    |

    ”Are Python programmers *that* lazy?” *--Some Java developer*

    |

    „Is it some Ruby thing?”

    |

    „WHAT?!?!”

    |

    „I don't think it should work ...”

-----

And last ...
============

Of course it has support for defaults!
--------------------------------------

.. sourcecode:: python

    class Pizza(Fields.name.crust["thing"].size["large"]):
        pass

.. sourcecode:: pycon

    >>> Pizza("Funghi", crust="thick")
    Pizza(name='Funghi', crust='thick', size='large')

Shameful plug
