* Replace all documentation which says "See PEP 585"
The following classes in the stdlib get simple updates:
- array.array
- asyncio.Future
- asyncio.Task
- collections.defaultdict
- collections.deque
- contextvars.ContextVar
- contextvars.Token
- ctypes.Array
- os.DirEntry
- re.Match
- re.Pattern
- string.templatelib.Interpolation
- string.templatelib.Template
- types.MappingProxyType
- queue.SimpleQueue
- weakref.ref
The following classes are documented publicly as functions, and are
therefore updated internally (`__class_getitem__.__doc__`) but not in the
public docs:
- functools.partial
- itertools.chain
The following builtin types have updates to `__class_getitem__.__doc__`
but not to any documentation pages:
- BaseExceptionGroup
- coroutines (from generators)
- dict
- enumerate
- frozendict
- frozenset
- generators (and async generators)
- list
- memoryview
- set
- slice
- tuple
Special cases:
- union objects are now documented as "supporting class-level []",
rather than anything to do with generics.
- Templates might be generic over a single type (union, in theory) or
over a TypeVarTuple. As this is not currently fully settled, it is
marked with a comment and a mild hint that it is a single type is used
(namely, "type" is singular rather than "types", plural)

* Correct several class getitem docs
And expand the text for tuples.

* Add notes on generic typing of builtins
* Fix typo in tuple.__class_getitem__ docstring
* Typo fix: malformed refs
Fix `generic` links which weren't marked as `:ref:`.
* Strike unnecessary docs on generic-ness

* Apply suggestions from code review
These are applied at both the originally indicated locations and in the
corresponding docstring definitions.

* Update Doc/library/re.rst

* Update Objects/enumobject.c

* Remove tuple generic doc in 'stdtypes' page
This is covered in more detail in the cross-linked typing documentation.
The other copy of this documentation -- in the docstring for
`tuple.__class_getitem__` -- is left in place.
* Fix whitespace around new doc of generics
Per review, do not introduce or remove whitespace such that section
breaks are altered by the introduction of doc on various generic types.
In most cases, this is a removal of an extra line.
In one case (Arrays), it is the reintroduction of a line.
Additionally, two other minor fixes are included:
- incorrect indent on 'defaultdicts'
- make `mappingproxy.__class_getitem__.__doc__` consistent with other
mapping type generic docs

* Move placement of memoryview generic note
Previous placement was at the end of the main docstring, which is
consistent with other types but places it after a section on various
methods (which makes it read somewhat inconsistently). Moving it up
helps resolve.

* Ensure sphinxdoc does not start sentences lowercase
Lowercase class names at the start of sentences are marked out with the
`class` role. In the case of `deque`, documentation already refers to
these as `Deques`, so this form is preferred.
* Apply suggestions from code review
Co-authored-by: Bénédikt Tran <10796600+picnixz@users.noreply.github.com>
* Fix line endings and wrap more tightly
Line endings fixed by pre-commit ; also re-wrapped the MappingProxyType
text which was too long.
* Use 'ContextVars' style in sphinx doc

In free-threaded builds, concurrent calls to PyDict_AddWatcher, PyDict_ClearWatcher, PyDict_Watch, and PyDict_Unwatch can race on the shared callback array and the per-dict watcher tags. This change adds a mutex to serialize watcher registration and removal, atomic operations for tag updates, and atomic acquire/release synchronization for callback dispatch in _PyDict_SendEvent.
* SEND specialization. Adds 2 new specialized instructions:
* SEND_VIRTUAL: for sends to virtual iterators e.g lists and tuples
* SEND_ASYNC_GEN: for sends to async generators
Tweak FOR_ITER_VIRTUAL so that SEND_VIRTUAL and FOR_ITER_VIRTUAL use equivalent guards
* Add Zd/Zf format support to array, memoryview and struct.
* ctypes: Replace F/D/G complex format with Zf/Zd/Zg.
* Modify array, ctypes and struct modules to support format strings
longer than 1 character (such as "Zd").
* Change array.typecodes type from str to tuple.
When someone adds a new type but doesn't increment
`_Py_MAX_MANAGED_STATIC_BUILTIN_TYPES` or
`_Py_MAX_MANAGED_STATIC_EXT_TYPES`, JIT tests fail,
because JIT builds define an extra type.
But the JIT tests don't necessarily run for the commit
that causes the failure.
As a workaround, use the same size for the array for all
builds, potentially with an empty spot.
Avoid racing with the owning thread's refcount operations when
immortalizing an interned string: if we don't own it and its refcount
isn't merged, intern a copy we own instead. Use atomic stores in
_Py_SetImmortalUntracked so concurrent atomic reads are race-free.
* Make the `PY_UNWIND` monitoring event available as a code-local
event to allow trapping on function exit events when an exception
bubbles up. This complements the PY_RETURN event by allowing to
catch any function exit event.
* Allow `PY_UNWIND` to be `DISABLE`d; disabling it disables the event for the whole code object.
* Do the above for `PY_THROW`, `RAISE`, `EXCEPTION_HANDLED`, and `RERAISE` events.
* Add FOR_ITER_VIRTUAL to specialize FOR_ITER for virtual iterators
* Add GET_ITER_SELF to specialize GET_ITER for iterators (including generators)
* Add GET_ITER_VIRTUAL to specialize GET_ITER for iterables as virtual iterators
* Add new (internal) _tp_iteritem function slot to PyTypeObject
* Put limited RESUME at start of genexpr for free-threading. Fix up exception handling in genexpr
