For the purposes of this table:

• Ordered:
  • array literals
  • unnamed parameter lists
  • named, order-dependent parameter lists (Swift)
• Unordered:
  • object literals with key-value pairs
  • named, order-independent parameter lists (Python)
  • designated initializers (Objective-C)
  • Builder pattern where the constructor doesn’t take latitude or longitude (Java)
  • GUI text fields that you can fill out in any order (Interface Builder)
