class_docstr: An OrderedSet is a custom MutableSet that remembers its order, so that
  every entry has an index that can be looked up.
  
  Example:
      >>> OrderedSet([1, 1, 2, 3, 2])
      OrderedSet([1, 2, 3])

docstr: Report whether another set contains this set.
  
  Example:
      >>> OrderedSet([1, 2, 3]).issubset({1, 2})
      False
      >>> OrderedSet([1, 2, 3]).issubset({1, 2, 3, 4})

      >>> OrderedSet([1, 2, 3]).issubset({1, 4, 3, 5})
