<note>
This isn't quite right. ExtensionClass checks for an '__of__'
method on a sub-object retrieved through an attribute access.
The '__of__' method, is defined for the sub-object, is called
to obtain the sub-object in the context of the container.
Acquisition.Implicit defined '__of__', not '__getattr__'.
The '__of__' protocol is *also* used for things like user-defined
method types and computed attributes.
