Currently, the "global interpreter lock" entry in the glossary mentions
that `-X gil 0` can be used to disable the GIL [1]. However, this is
invalid; the correct usage should be `-X gil=0`.
$ python -X gil 0 -c 'print("Hello, world")'
Fatal Python error: config_read_gil: PYTHON_GIL / -X gil must be "0" or "1"
Python runtime state: preinitialized
$ python -X gil=0 -c 'print("Hello, world")'
Hello, world

In the datastructures tutorial doc, some operations are described as
"equivalent to" others. This has led to some user-confusion -- at
least in the Discourse forums -- about cases in which the operations
differ.
This change doesn't systematically eliminate the word "equivalent"
from the tutorial. It just substitutes "similar to" in several cases
in which "equivalent to" could mislead users into expecting exact
equivalence.
In some locales (like French or Hebrew) the full or abbreviated names of
the default month and weekday used in __calc_date_time can be part of
other name or constant part of the %c format. The month name can also
match %m with constant suffix (like in Japanese). So the code failed to
correctly distinguish formats %a, %A, %b, %B and %m.
Cycle all month and all days of the week to find the variable part
and distinguish %a from %A and %b from %B or %m.
Fixed locales for the following languges:
Arabic, Bislama, Breton, Bodo, Kashubian, Chuvash, Estonian, French, Irish,
Ge'ez, Gurajati, Manx Gaelic, Hebrew, Hindi, Chhattisgarhi, Haitian Kreyol,
Japanese, Kannada, Korean, Marathi, Malay, Norwegian, Nynorsk, Punjabi,
Rajasthani, Tok Pisin, Yoruba, Yue Chinese, Yau/Nungon and Chinese.

This follows GNU gzip, which defaults to using 0 as the mtime
for compressing stdin, where no file mtime is involved.
This makes the output of gzip.compress() deterministic by default,
greatly helping reproducible builds.

Raise ValueError in add_argument() if either explicit nargs=0 or action
that does not consume arguments (like 'store_const' or 'store_true') is
specified for positional argument.
Also improve the documentation. Specify how dest and metavar are derived
from add_argument() positional arguments.

Previously, all nested mutually exclusive groups lost their connection
to the group containing them and were displayed as belonging directly
to the parser.

When formatting the AST as a string, infinite values are replaced by
1e309, which evaluates to infinity. The initialization of this string
replacement was not thread-safe in the free threading build.
- Move some Structure tests to test_structunion; use a common base
test class + two subclasses to run them on Union too
- Remove test_union for now as it's redundant
Note: `test_simple_structs` & `test_simple_unions` are in the common
file because they share `formats`.
memcopy'ing arbitrary values to _Bool variable triggers undefined
behaviour. Avoid this.
We assume that `false` is represented by all zero bytes.

* Add definitions for "context", "current context", and "context
management protocol".
* Update related definitions to be consistent with the new
definitions.
* Restructure the documentation for the `contextvars.Context` class
to prepare for adding context manager support, and for consistency
with the definitions.
* Use `testcode` and `testoutput` to test the `Context.run` example.
* Expand the documentation for the `Py_CONTEXT_EVENT_ENTER` and
`Py_CONTEXT_EVENT_EXIT` events to clarify and to prepare for
planned changes.
