I think the opposite is true.


As shown in the "Versions" field in the issue, this bug is Python 2 specific, so there is nothing to do with Python 3.

My point is not on 'dict', but on 'set'. So the history of 'dict' doesn't care.

As we can see there are names for:
- 'None' (types.NoneType)
- 'bool' (types.BooleanType)
- 'int' (types.IntType)
- 'long' (types.LongType)
- 'float' (types.FloatType)
- 'complex' (types.ComplexType)
- etc.

and more importantly:
- 'tuple' (types.TupleType)
- 'list' (types.ListType)
- 'dict' (types.DictType)

and since 'set' is also considered a built-in type (see https://docs.python.org/2/library/stdtypes.html), I can't see the reason WHY it is not considered a bug without having 'set' (types.SetType) in the module.
