/**
* Returns the result of calling its first argument with the remaining
* arguments. This is occasionally useful as a converging function for
* `R.converge`: the left branch can produce a function while the right branch
* produces a value to be passed to that function as an argument.
*
* @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
*
* 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),
* R.prop('value')
* ]);
*
* format({indent: 2, value: 'foo\nbar\nbaz\n'}); //=> ' foo\n bar\n baz\n'
