/**
* 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
*
* const indentN = R.pipe(R.repeat(' '),
* R.join(''),
* R.replace(/^(?!$)/gm));
*
* const format = R.converge(R.call, [
* R.pipe(R.prop('indent'), indentN),
* R.prop('value')
* ]);
*
* format({indent: 2, value: 'foo\nbar\nbaz\n'}); //=> ' foo\n bar\n baz\n'
* @symb R.call(f, a, b) = f(a, b)
