/**
 * Returns the result of calling its first argument with the remaining
 * arguments. This is occasionally useful as a converging function for
 * [`R.converge`](#converge): the first branch can produce a function while the
 * remaining branches produce values to be passed to that function as its
 * arguments.
 *
 * @func
 * @memberOf R
 * @since v0.9.0
 * @category Function
 * @sig (*... -> a),*... -> a
 * @param {Function} fn The function to apply to the remaining arguments.
 * @param {...*} args Any number of positional arguments.
 * @return {*}
 * @see R.apply
 * @example
 *
 *      R.call(R.add, 1, 2); //=> 3
 *
 *      var indentN = R.pipe(R.times(R.always(' ')),
 *                           R.join(''),
 *                           R.replace(/^(?!$)/gm));

 *      var format = R.converge(R.call, [
 *                                  R.pipe(R.prop('indent'), indentN),
