Old-style classes are discarded and hierarchies rooted on them

S( s Ensure basic interface compliance for an instance or dict of callables.
Checks that ``obj`` implements public methods of ``cls`` or has members
listed in ``methods``. If ``required`` is not supplied, implementing at
least one interface method is sufficient. Methods present on ``obj`` that
are not in the interface are ignored.
If ``obj`` is a dict and ``dict`` does not meet the interface
requirements, the keys of the dictionary are inspected. Keys present in
``obj`` that are not in the interface will raise TypeErrors.
Raises TypeError if ``obj`` does not meet the interface criteria.
In all passing cases, an object with callable members is returned. In the
simple case, ``obj`` is returned as-is; if dict processing kicks in then
an anonymous class is returned.
obj
A type, instance, or dictionary of callables.
cls
Optional, a type. All public methods of cls are considered the
interface. An ``obj`` instance of cls will always pass, ignoring
``required``..
methods
Optional, a sequence of method names to consider as the interface.
required
Optional, a sequence of mandatory implementations. If omitted, an
``obj`` that provides at least one interface method is considered
sufficient. As a convenience, required may be a type, in which case
all public methods of the type are required.

>>> symbol('foo') is symbol('foo')
True

A slight refinement of the MAGICCOOKIE=object() pattern. The primary
advantage of symbol() is its repr(). They are also singletons.
Repeated calls of symbol('name') will all return the same instance.
The optional ``doc`` argument assigns to ``__doc__``. This
is strictly so that Sphinx autoattr picks up the docstring we want
(it doesn't appear to pick up the in-module docstring if the datamember
is in a different module - autoattribute also blows up completely).
If Sphinx fixes/improves this then we would no longer need
``doc`` here.
