Description: plucky: concise deep obj.get()
        ==============================
        
        ``plucky.pluck`` enables you to safely extract several-levels deep values by 
        using a concise selector comprised of dictionary-like keys and list-like 
        indices. Slices over list items are also supported.
        
        ``plucky.pluckable`` will happily wrap dictionary- or list-like objects and allow
        for chained soft plucking with attribute and item getters (e.g. ``.attr``,
        ``["key"]``, ``[idx]``, ``[a:b]``, or a combination: ``["key1", "key2"]``,
        and ``[0, 3:7, ::-1]``)
        
        ``plucky.merge`` facilitates recursive merging of two data structures, reducing
        leaf values with the provided binary operator.
        
        
        Installation
        ------------
        
        ``plucky`` is available as a **zero-dependency** Python package. Install with::
        
            $ pip install plucky
        
        
        Usage
        -----
        
        .. code-block:: python
        
            from plucky import pluck, merge, pluckable
        
            pluck(obj, 'selector.*.path.2')
        
            merge({"x": 1, "y": 0}, {"x": 2})
            
            pluckable(obj).users[2:5, 10:15].name["first", "middle"]
        
        
        Examples
        --------
        
        .. code-block:: python
        
            obj = {
                'users': [{
                    'uid': 1234,
                    'name': {
                        'first': 'John',
                        'last': 'Smith',
                    }
                }, {
                    'uid': 2345,
                    'name': {
                        'last': 'Bono'
                    }
                }]
            }
        
            pluck(obj, 'users.1.name')
            # -> {'last': 'Bono'}
        
            pluck(obj, 'users.*.name.last')
            # -> ['Smith', 'Bono']
        
            pluck(obj, 'users.*.name.first')
            # -> ['John']
        
        
        More Examples! :)
        -----------------
        
        .. code-block:: python
        
            pluck([1,2,3], '2')
            # -> 3
        
            pluck([1,2,3], '-1')
            # -> 3
        
            pluck([1,2,3], '*')
            # -> [1,2,3]
        
            pluck([1,2,3], '-2:')
            # -> [2,3]
        
            pluck([1,2,3], '::-1')
            # -> [3,2,1]
        
            pluck([1, {'val': 2}, 3], '*.val')
            # -> [2]
        
            pluck([1, {'val': [1,2,3]}, 3], '1.val.-1')
            # -> 3
        
            merge({"x": 1, "y": 0}, {"x": 2})
            # -> {"x": 3, "y": 0}
        
            merge({"a": [1, 2], "b": [1, 2]}, {"a": [3, 4], "b": [3]})
            # -> {"a": [4, 6], "b": [1, 2, 3]}
        
            pluckable(obj).users.name.last.value
            # -> ['Smith', 'Bono']
        
            pluckable(obj).users[:, ::-1].name.last.value
            # -> ['Smith', 'Bono', 'Bono', 'Smith']
            
            pluckable(obj).users[:, ::-1].name.last[0, -1].value
