bpo-44353: Correct docstring for NewType (#29785) 
The docstring for `typing.NewType` is no longer strictly accurate, now that `NewType` is a class, rather than a function

bpo-44524: Do not set _name of _SpecialForm without need (GH-27861)

bpo-44793: Fix checking the number of arguments when subscribe a generic type with ParamSpec parameter. (GH-27515) 
For example Callable[P, T][[int], str, float] will now raise an error.

Use also term "arguments" instead of "parameters" in error
message for too few/many arguments.

bpo-41249: Fix postponed annotations for TypedDict (GH-27017) 
This fixes TypedDict to work with get_type_hints and postponed evaluation of annotations across modules.

This is done by adding the module name to ForwardRef at the time the object is created and using that to resolve the globals during the evaluation.

bpo-38291: Fix a spurious warning when using help(object) (#27039) 
help(object) via pydoc.TextDoc.docclass(object) iterates over the
subclasses of object, which includes typing.io and typing.re if typing
is imported. It tries to access cls.__module__ for each of those
sub-classes. This change suppresses warnings when accessing
cls.__module__.

bpo-44098: Drop ParamSpec from most `__parameters__` in typing generics (GH-26013) 
Added two new attributes to ``_GenericAlias``: 
* ``_typevar_types``, a single type or tuple of types indicating what types are treated as a ``TypeVar``. Used for ``isinstance`` checks.
* ``_paramspec_tvars ``, a boolean flag which guards special behavior for dealing with ``ParamSpec``. Setting it to ``True`` means this  class deals with ``ParamSpec``.

bpo-43901: Lazy-create an empty annotations dict in all unannotated user classes and modules (#25623) 
Change class and module objects to lazy-create empty annotations dicts on demand.  The annotations dicts are stored in the object's `__dict__` for backwards compatibility.
