Compare *self* to *other* based on ``__name__`` and ``__module__``.
Return 0 if they are equal, return 1 if *self* is
greater than *other*, and return -1 if *self* is less than
*other*.
If *other* does not have ``__name__`` or ``__module__``, then
return ``NotImplemented``.
.. caution::
This allows comparison to things well outside the type hierarchy,
perhaps not symmetrically.
For example, ``class Foo(object)`` and ``class Foo(Interface)``
in the same file would compare equal, depending on the order of
operands. Writing code like this by hand would be unusual, but it could
happen with dynamic creation of types and interfaces.
None is treated as a pseudo interface that implies the loosest
contact possible, no contract. For that reason, all interfaces
sort before None.

An interface specification is used to track interface declarations
and component registrations.
This class is a base class for both interfaces themselves and for
interface specifications (declarations).
Specifications are mutable. If you reassign their bases, their
relations with other specifications are adjusted accordingly.

Convert a method specification to an actual method of the interface.
This is a decorator that functions like `staticmethod` et al.
The primary use of this decorator is to allow interface definitions to
define the ``__adapt__`` method, but other interface methods can be
overridden this way too.
