Here's dir(types), in Python 2.6.5:

['BooleanType', 'BufferType', 'BuiltinFunctionType',
'BuiltinMethodType', 'ClassType', 'CodeType', 'ComplexType',
'DictProxyType', 'DictType', 'DictionaryType', 'EllipsisType',
'FileType', 'FloatType', 'FrameType', 'FunctionType', 'GeneratorType',
'GetSetDescriptorType', 'InstanceType', 'IntType', 'LambdaType',
'ListType', 'LongType', 'MemberDescriptorType', 'MethodType',
'ModuleType', 'NoneType','NotImplementedType', 'ObjectType',
'SliceType', 'StringType', 'StringTypes', 'TracebackType', 'TupleType',
'TypeType', 'UnboundMethodType', 'UnicodeType', 'XRangeType',
'__builtins__', '__doc__', '__file__', '__name__', '__package__']

Seems to be missing SetType, FrozenSetType, BytesType, and
ByteArrayType. Anything else missing?

(Arguably, "bytes" isn't really distinguished until 3.x, but
still...)

IIUC, since Python 2.2ish you can't treat the types module as
comprehensive. It exists as a remnant from the time when there was a
difference between types and classes.

Sets and the recent additions exist solely in this new world where we
just isinstance(blah, set) or issubclass or whatnot.

Ah. That makes sense.

Does the "types" module go away in 3.x, then?

Not entirely, but it is greatly reduced.
