- Update to 1.2.0
* Function nodes can detect decorator call chain and see if they are
decorated with builtin descriptors (`classmethod` and `staticmethod`).
* infer_call_result called on a subtype of the builtin type will now
return a new `Class` rather than an `Instance`.
* `Class.metaclass()` now handles module-level __metaclass__ declaration
on python 2, and no longer looks at the __metaclass__ class attribute on
python 3.
* Function nodes can detect if they are decorated with subclasses
of builtin descriptors when determining their type
(`classmethod` and `staticmethod`).
* Add `slots` method to `Class` nodes, for retrieving
the list of valid slots it defines.
* Expose function annotation to astroid: `Arguments` node
exposes 'varargannotation', 'kwargannotation' and 'annotations'
attributes, while `Function` node has the 'returns' attribute.
* Backported most of the logilab.common.modutils module there, as
most things there are for pylint/astroid only and we want to be
able to fix them without requiring a new logilab.common release
* Fix names grabed using wildcard import in "absolute import mode"
(ie with absolute_import activated from the __future__ or with
python 3). Fix pylint issue #58.
* Add support in pylint-brain for understanding enum classes.
