Access the loop iterator value

Access the iterator value when a list is printed into a document.

Example

In {d[i].cars[i].other.wheels[i].tire.subObject:add(.i):add(..i):add(...i)}

The number of dots equals the number of previous i:

• .i matches the index value of wheels[i]

• ..i matches the index value of cars[i]

• ...i matches the index value of d[i]
