/**
 * Returns `true` if all elements of the list match the predicate, `false` if
 * there are any that don't.
 *
 * Dispatches to the `all` method of the second argument, if present.
 *
 * Acts as a transducer if a transformer is given in list position.
 *
 * @func
 * @memberOf R
 * @since v0.1.0
 * @category List
 * @sig (a -> Boolean) -> [a] -> Boolean
 * @param {Function} fn The predicate function.
 * @param {Array} list The array to consider.
 * @return {Boolean} `true` if the predicate is satisfied by every element, `false`
 *         otherwise.
 * @see R.any, R.none, R.transduce
 * @example
 *
 *      const equals3 = R.equals(3);
 *      R.all(equals3)([3, 3, 3, 3]); //=> true
 *      R.all(equals3)([3, 3, 1, 3]); //=> false
