…annotate_function As noted on the issue, making get_annotate_function() support both types and mappings is problematic because one object may be both. So let's add a new one that works with any mapping. This leaves get_annotate_function() not very useful, so remove it.

| .. function:: get_annotate_from_class_namespace(namespace) | ||
|
|
||
| Retrieve the :term:`annotate function` for *obj*. Return :const:`!None` | ||
| if *obj* does not have an annotate function. *obj* may be a class, function, | ||
| module, or a namespace dictionary for a class. The last case is useful during | ||
| class creation, e.g. in the ``__new__`` method of a metaclass. | ||
|
|
||
| This is usually equivalent to accessing the :attr:`~object.__annotate__` | ||
| attribute of *obj*, but access through this public function is preferred. | ||
| Retrieve the :term:`annotate function` from a class namespace dictionary *namespace*. | ||
| Return :const:`!None` if the namespace does not contain an annotate function. | ||
| This is useful in :ref:`metaclasses <metaclasses>` to retrieve the annotate function; | ||
| see :ref:`below <annotationlib-metaclass>` for an example. |

I was briefly confused between the class' __dict__ (which might not exist, e.g. __slots__) and the class namespace dictionary during creation etc. Is it worth clarifying? I appreciate this is fairly advanced functionality & I am skim-reading here, so maybe best leaving as is.
