#13783: Set Partitions, either a bug or something is unclear.

-----------------------------+----------------------------------------------
Consider the following code. The first is an example of not being able to
verify the type Set Partition, the second is an analogous example with
Permutations. Please advise on this discrepancy and how to get around it.
> sage: sp = SetPartitions(5).random_element()
> sage: sp
{{5}, {2, 3}, {1, 4}}
> sage: type(sp)
<class 'sage.sets.set.Set_object_enumerated_with_category'>
> sage: type(sp) == Set_object_enumerated_with_category
----------------------------------------------- NameError
Traceback (most recent call last)

> sage:
> sage:
> sage: p = Permutations(5).random_element()
> sage: p

> sage: type(p)
<class 'sage.combinat.permutation.Permutation_class'>
> sage: type(p) == Permutation_class
True
