> 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.
