* Implement _collections.OrderedDict
Extracted from #6799: native OrderedDict as a dict subclass,
iterator mutation tracking, and mapping-view set operations.
* Add OrderedDict, warnings source lines, and socket sendmsg
Implement _collections.OrderedDict as a dict subclass with a
linked list of insertion-order nodes.
Pack struct F/D as native float/double complex pairs, and report
unexpected __replace__ field names as a list repr.
Register encodings.latin_1 at startup. Reject NUL in input()
prompts. Copy non-exact type dicts in mapping order.
Fetch warning source lines through _bless_my_loader and unicode
splitlines. Keep the last warnings.filters list after deletion.
Snapshot sendmsg sequences before converting buffers, parse
ancillary ints with __index__, and dispatch AF_CAN by protocol.
Store sys.trace and sys.profile on each ThreadSlot so
_settraceallthreads/_setprofileallthreads are visible to
sys.gettrace/getprofile on other threads.
Use <frozen importlib._bootstrap> as frozen importlib
co_filename. Keep HEAPTYPE socket objects GC-tracked.

* Load marshal via readinto and dump sets in dumps order
marshal.load fills a scratch buffer with readinto on a
contiguous writable memoryview, and rejects a returned length
other than the requested size.
set and frozenset dumps write elements in sorted(v,
key=marshal.dumps) order.

* Add classmethod_descriptor and ABC IS_ABSTRACT flags
Give METH_CLASS methods a distinct classmethod_descriptor type.
Store Py_TPFLAGS_IS_ABSTRACT from __abstractmethods__ and look
up that attribute only in the type's own dict.
Expose defaultdict.default_factory as a member descriptor.
Inherit bool's unused number slots from int. Mark set and
frozenset __contains__ as METH_COEXIST.
Parse classmethod, staticmethod, object.__new__, and heap type
text signatures. Register interactive source in linecache.

* address review: odict reuse, descr call, new wrapper
Reuse odict node slots and walk the live list in next_after.
Require both | operands to be dicts. Drop the odict iterator
on GC clear. Bind classmethod descriptors through descr_get
and update IS_ABSTRACT under the type lock. Give odict keys
and items sq_contains. Walk tp_new_wrapper past new_wrapper
so HEAPTYPE socket subclasses can call socket.__new__.

* Add pickle and os.stat inspect signatures
Give _pickle.Pickler the clinic constructor text signature and
accept fix_imports and buffer_callback as positional-or-keyword.
Allow #[pyfunction(text_signature)] and use it so os.stat reports
(path, *, dir_fd=None, follow_symlinks=True). Uncomment import
_pickle and drop the pickle inspect expectedFailures.

pass.

* Add ExceptionGroup fields and OSError use-init
BaseExceptionGroup stores msg, excs, and excs_str; args keep
the original sequence. OSError defers parse when a subclass
overrides only __init__. characters_written can be deleted.
Exception args/traceback/cause/context reject invalid
setattr/delattr. UnicodeError.object is a deletable field.

SyntaxError.__init__ clears omitted location attributes.

Indentation errors outrank print/exec missing-parentheses.
BOM-with-non-utf8, bytes literals, and global+nonlocal now
report the same offsets as the parser/symtable.

compile_block_expression, and compile_expression forwarders; compile_top
stays as the entry point.
Stash an escalated compiler SyntaxWarning so a non-SyntaxWarning category

derived from it via bits(); parser input modes stay plain consts.

- frame.rs: compute the MATCH_CLASS class name lazily so a successful
match no longer takes the type name lock or allocates; the
__match_args__-not-a-tuple branch reuses it instead of recomputing.

label ("maximum recursion depth exceeded during compilation").
- sys.set_int_max_str_digits: restore the "maxdigits must be 0 or larger
than {n}" error text.

into ensure_excepthandler_node.

* Correct complex real subtract op
* Remove unnecessary vm arugment
* rewrite finalize_modules with phased algorithm
Replace the absence of module finalization during interpreter shutdown
with a 5-phase algorithm matching pylifecycle.c finalize_modules():
1. Set special sys attributes to None, restore stdio
2. Set all sys.modules values to None, collect module dicts
3. Clear sys.modules dict
4. Clear module dicts in reverse import order (2-pass _PyModule_ClearDict)
5. Clear sys and builtins dicts last
This ensures __del__ methods are called during shutdown and modules are
cleaned up in reverse import order without hardcoded module names.
* dealloc the rigth way
* fix finalize_modules: only clear __main__ dict, mark daemon thread tests as expected failure
Without GC, clearing all module dicts during finalization causes __del__
handlers to fail (globals are None). Restrict Phase 4 to only clear
__main__ dict — other modules' globals stay intact for their __del__
handlers.
Mark test_daemon_threads_shutdown_{stdout,stderr}_deadlock as expected
failures — without GC+GIL, finalize_modules clears __main__ globals
while daemon threads are still running.

Initially this is only meant to be a small update for `test_io.py`.
But it turns out that `test.support` need a lot of cleanup especially
for `test.support.warnings_helper`.
The remaining failures are due to what appears to be a fundamental
difference between how RustPython and CPython handle surrogate
characters/codepoints-which-aren't-characters. They are wrapped with
`self.assertRaises(AssertionError)` so we will notice once they start
passing.
https://github.com/RustPython/RustPython/issues/935 is most likely
related.
