/**
* Returns a new list by plucking the same named property off all objects in
* the list supplied.
*
* `pluck` will work on
* any [functor](https://github.com/fantasyland/fantasy-land#functor) in
* addition to arrays, as it is equivalent to `R.map(R.prop(k), f)`.
*
* @func
* @memberOf R
* @since v0.1.0
* @category List
* @sig Functor f => k -> f {k: v} -> f v
* @param {Number|String} key The key name to pluck off of each object.
* @param {Array} f The array or functor to consider.
* @return {Array} The list of values for the given key.
* @see R.props
* @example
*
* var getAges = R.pluck('age');
* getAges([{name: 'fred', age: 29}, {name: 'wilma', age: 27}]); //=> [29, 27]
*
* R.pluck(0, [[1, 2], [3, 4]]); //=> [1, 3]
* R.pluck('val', {a: {val: 3}, b: {val: 5}}); //=> {a: 3, b: 5}
* @symb R.pluck('x', [{x: 1, y: 2}, {x: 3, y: 4}, {x: 5, y: 6}]) = [1, 3, 5]
* @symb R.pluck(0, [[1, 2], [3, 4], [5, 6]]) = [1, 3, 5]
