Given that you can register adapters for any class, whether or not it
implements any interface, this doesn't work as it should:
>>> from zope.component import provideAdapter
>>> def adapter(*args): pass
...
>>> from zope.interface import Interface
>>> class ITest(Interface): pass
...
>>> provideAdapter(adapter,adapts=(None,),provides=ITest)
>>> ITest(1)
Traceback (most recent call last):
...
TypeError: ('Could not adapt', 1, <InterfaceClass __main__.ITest>)
>>> class test: pass
...
>>> ITest(test())
...
TypeError: ('Could not adapt', <__main__.test instance at ...>,
<InterfaceClass __main__.ITest>)

Where can I find the docs and interfaces you mention above? I looked
through both zope.interface and zope.component and obviously missed them :-(
