[Python-Dev] Why are there no 'set' and 'frozenset' types in the 'types' module?

Because there's no reason to include them, since they are already in
the root (builtins) namespace.

You'll notice that in Python 3, the "types" module only contains types
which are not obviously accessed through easier means:

>>> dir(types)
['BuiltinFunctionType', 'BuiltinMethodType', 'CodeType', 'FrameType',
'FunctionType', 'GeneratorType', 'GetSetDescriptorType', 'LambdaType',
'MemberDescriptorType', 'MethodType', 'ModuleType', 'TracebackType',
'__builtins__', '__cached__', '__doc__', '__file__', '__name__',
'__package__']
