1. Remove conditions already checked by assert()
2. Remove object_init() call that effectively creates an empty tuple and
checks that this tuple is empty
The _bootstrap_inner() method of threading.Thread now reuses its
_delete() method rather than accessing _active() directly. It became
possible since _active_limbo_lock became reentrant. Moreover, it no
longer ignores any exception when deleting the thread from the
_active dictionary.
* Remove struct _node from the stable ABI list
This struct was removed along with the old parser in Python 3.9 (PEP 617)
* Stable ABI list: Use the public name "PyFrameObject" rather than "_frame"
* Ensure limited API doesn't contain private names
Names prefixed by an underscore are private by definition.
* Add a blurb
Currently, if an arg value escapes (into the closure for an inner function) we end up allocating two indices in the fast locals even though only one gets used. Additionally, using the lower index would be better in some cases, such as with no-arg `super()`. To address this, we update the compiler to fix the offsets so each variable only gets one "fast local". As a consequence, now some cell offsets are interspersed with the locals (only when an arg escapes to an inner function).

* Move connection type to global state
* Move cursor type to global state
* Move prepare protocol type to global state
* Move row type to global state
* Move statement type to global state
* ADD_TYPE takes a pointer
* pysqlite_get_state is now static inline
* Simplify the count_vowels example
* Hits and misses are fetched while a lock is held
* Add note that references are kept for arguments and return values
* Clarify behavior when *typed* is false.
Change the behaviour of `math.pow(0.0, -math.inf)` and `math.pow(-0.0, -math.inf)` to return positive infinity instead of raising `ValueError`. This makes `math.pow` consistent with the built-in `pow` (and the `**` operator) for this particular special case, and brings the `math.pow` special-case handling into compliance with IEEE 754.
by-value lookups could fail on complex enums, necessitating a check for
__reduce__ and possibly sabotaging the final enum;
by-name lookups should never fail, and sabotaging is no longer necessary
for class-based enum creation.
This enables, for example, two base Enums to both inherit from `str`, and then both be mixed into the same final Enum:
class Str1Enum(str, Enum):
# some behavior here
class Str2Enum(str, Enum):
# some more behavior here
class FinalStrEnum(Str1Enum, Str2Enum):
# this now works
