[] (access)

Description
To access a specified element of a list by position use A_LIST[Index]. Index is the position of the element you want to access starting at 0, so the first element has index 0, the second index 1 and so on.
Examples
["First", "Second", "Third"][0]
This creates a simple list of three elements and returns the first one.
p is Person
p.nationalities[0]
This returns the first nationality a person has. 
If the person has no nationalities this rule will fail. So if you don't know if a person will have nationalities at all add checks. E.g. check if the list is long enough:
if count(p.nationalities) > 0 then 
  p.nationalities[0]
else
  'No nationality'
end
