Assisted-by: Grok:4.7
Clippy doesn't run on everything which is why I keep accidentally
uncovering new lints to fix. I updated CI to run clippy on all features,
except tk, as well as all binaries, examples, and tests. That should
cover everything.
Tk currently doesn't build (at least for me), so that feature is still
disabled in CI.
While here, fix some of the lints that are now raised.
* Bound AST nesting so deep source raises instead of crashing
Deeply nested source exhausted the native stack and killed the process
with SIGSEGV, which no Python-level `except` can catch.
The parser grows its own stack when it runs low on one, so it returns
trees deeper than the passes after it can walk. Those passes recurse
without a limit of their own, and the symbol table, which does apply
one, runs last. `compile(..., PyCF_ONLY_AST)` returns before reaching
it at all.
Apply that same limit to the tree right after it is parsed, and count
bracket nesting before parsing rather than after, as CPython's
tokenizer does. Checking afterwards built the tree first, and one
nested that deep exhausts the stack when it is dropped.

* Return Result from too_deeply_nested_error
Lets the four call sites use `?` instead of matching on `Some` and
returning the error by hand, which drops 11 lines. `Result` is already

* Drop exceeds_max_nesting for the check beside it
The escape-warning pass needs the bracket check but had no `SourceFile` to
build a `CompileError` from, so it got a `bool` wrapper of its own. Building
the `SourceFile` there lets it call `pre_parse_source_error` instead, which
is shaped like the other checks in that file, and costs nothing measurable.

* Report errors from #[pyclass] trait items
The trait branch of impl_pyclass_impl built its own ImplContext, so the

the class without a compile error. The trait branch now uses the shared

* Set builtin __doc__, __module__, and datetime signatures
Expose empty doc-db member entries as ''. Heap __dict__ and __weakref__
getsets carry their descriptor docs. Member repr uses the qualified

__module__ is collections for the deque iterators, _csv for Dialect,
ctypes for ArgumentError and CField, _lzma for LZMAError, operator for
the getter types, pickle for PickleBuffer, _ssl for MemoryBIO,
SSLSession, _SSLContext and _SSLSocket, weakref for the proxy types,

unicodedata's copied UCD functions set __module__ to unicodedata.
_testinternalcapi function docs and weakproxy.__str__ use the stored

None, and fromisoformat and tzinfo methods name the parameter object.

* Record native docstrings the doc DB generator skipped
- Stop ignoring `__dir__`; skip `__base__`, `__bases__` and `__module__` instead.
- Recurse into native classes whose metaclass is not `type`, and also key a
class stored under another attribute name by its own `__name__`.
- Collect native objects exposed by pure-Python modules, such as the codec
error handlers, under their own `__module__` and `__name__`.
- Key types found through `object.__subclasses__()` by their own module as
well as `builtins`.
- Record getset/member descriptors named like class metadata
(`coroutine.__name__`), and native types a module exposes only through an
instance (`sys.flags`).
- Treat a class as native only when it owns its C descriptors, so an enum
holding a copied `str.__format__` is skipped.
- Keep docstrings unstripped, and import every module in sorted order before
walking them.

Member definitions carry an internal `PY_ATOMIC` flag taken from

`subs_parameters` reads type names only for the error. The unraisable
hook prints `<unknown>` when `__module__` fails or is not a str. The

* Read type.__module__ from the dict only for heap types
A static type's `__module__` is the text before the last `.` of its name,
or `builtins`. A heap type reads its dict and raises `AttributeError`
when the entry is missing; `type` and `object` reprs ignore that error.
`type()` no longer stores `__module__ = None` when the caller's globals
have no `__name__`.
`#[pyexception(module = ...)]` now reaches the type name, and static
types that relied on a dict `__module__` (ast nodes, pyexpat, ssl,
_hashlib and _interpchannels errors, ExceptionGroup) carry their module.

Static types carry their `tp_itemsize` (`type`, `memoryview`, `code`,

* Address builtin members by field offset
`#[pymember]` now declares a field of the payload and generates a
PyMemberDef whose offset is the payload offset plus the field offset.
The getter/setter function form and `MemberAccess::Func` are removed;
builtin, slot, and C-API members share one get/set path. The macro
checks the field type against the member type.
Converted members: property fget/fset/fdel/__doc__, function
__globals__/__closure__/__builtins__/__doc__/__module__, staticmethod
and classmethod __func__/__wrapped__, complex real/imag (T_DOUBLE),
frame f_trace_lines (T_BOOL), defaultdict default_factory, getset and
member descriptor __name__/__objclass__, module __dict__.
frame.f_trace_opcodes is a getset.
Writable member fields are atomic pointer cells. The instance dict
pointer is an atomic cell at a fixed offset in front of the object,
and dict presence follows the type's HAS_DICT flag. The pickle
basicsize check no longer counts dict, weakref, and slot storage,
which live outside the payload.

`default_factory` is None.

`#[pyclass]` builds `PyClassDef::MEMBERS`, a static `PyMemberSpec`
table, and `extend_class` registers one member descriptor per entry.
`path` addresses a subfield, one field may carry several members, and a
`#[cfg]` on the field gates its entry. The impl-side const form is
removed and now a compile error.

* Split nullable and non-null atomic cells
The nullable cell API (`new_empty`, `load_owned`, `store`,

`PyAtomicRef<Option<PyObject>>`, and the typed `PyAtomicRef<Option<T>>`
shares it. The non-null `PyAtomicRef<PyObject>` gets `load_owned` and
`store` that return the object directly.
Slot cells, property fget/fset/fdel/__doc__, and defaultdict
default_factory are nullable cells. staticmethod and classmethod
callable are non-null cells and are read without `unwrap`. The
instance dict cell is `PyAtomicRef<Option<PyDict>>`, so reading it no
longer downcasts.
