> pairs() function returns an array of arrays describing fields of input
> object, including nested fields.
> For each field of the input_object the returned array contains an array with
> two elements.
> The first element is the name and the second one is the value of the input
> object's field.
> The input object is introspected recursively, so all fields of its nested
> objects are returned.
> Nested objects contained in arrays and multisets are also processed by this
> function.
