Description

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.
