    Produces a class that either can be used standalone or as a base class for persistent classes.

    This is a thin wrapper around a named tuple.

    Constructing a type and using it to instantiate objects:

    >>> Point = immutable('x, y', name='Point')
    >>> p = Point(1, 2)
    >>> p2 = p.set(x=3)
    >>> p
    Point(x=1, y=2)
    >>> p2
    Point(x=3, y=2)

    Inheriting from a constructed type. In this case no type name needs to be supplied:

    >>> class PositivePoint(immutable('x, y')):
    ...     __slots__ = tuple()
    ...     def __new__(cls, x, y):
    ...         if x > 0 and y > 0:
    ...             return super(PositivePoint, cls).__new__(cls, x, y)
    ...         raise Exception('Coordinates must be positive!')
    ...
    >>> p = PositivePoint(1, 2)
    >>> p.set(x=3)
    PositivePoint(x=3, y=2)
    >>> p.set(y=-3)
    Traceback (most recent call last):
    Exception: Coordinates must be positive!

    The persistent class also supports the notion of frozen members. The value of a frozen member
    cannot be updated. For example it could be used to implement an ID that should remain the same
    over time. A frozen member is denoted by a trailing underscore.

    >>> Point = immutable('x, y, id_', name='Point')
    >>> p = Point(1, 2, id_=17)
    >>> p.set(x=3)
    Point(x=3, y=2, id_=17)
    >>> p.set(id_=18)
    Traceback (most recent call last):
