The same change was made, and for the same reason, by ``argparse`` back in
2017. The ``textwrap`` module is only used when printing help text, so most
invocations will never need it imported.

``gettext`` is often imported in programs that may not end up translating
anything. In fact, the ``struct`` module already has a delayed import when
parsing ``GNUTranslations`` to speed up the no ``.mo`` files case. The re module
is also used in the same situation, but behind a function chain only
called by ``GNUTranslations``.
Cache the compiled regex globally the first time it is used. The
finditer function is converted to a method call on the compiled
object which is slightly more efficient, and necessary for the
delayed re import.
Email generators using email.policy.default could incorrectly omit the
quote ('"') characters from a quoted-string during header refolding,
leading to invalid address headers and enabling header spoofing. This
change restores the quote characters on a bare-quoted-string as the
header is refolded, and escapes backslash and quote chars in the string.

This reduces the import time of the `csv` module by up to five times,
by importing `re` on demand.
In particular, the `re` module is no more implicitly exposed as `csv.re`.
* gh-128916: Do not set `SO_REUSEPORT` on non-`AF_INET*` sockets
Do not attempt to set ``SO_REUSEPORT`` on sockets of address familifies other
than ``AF_INET`` and ``AF_INET6``, as it is meaningless with these address
families, and the call with fail with Linux kernel 6.12.9 and newer.

tracemalloc_alloc(), tracemalloc_realloc(), tracemalloc_free(),
_PyTraceMalloc_TraceRef() and _PyTraceMalloc_GetMemory() now check
'tracemalloc_config.tracing' after calling TABLES_LOCK().
_PyTraceMalloc_TraceRef() now always returns 0.

Importing `pickle` is now roughly 25% faster.
Importing the `re` module is no longer needed and
thus `re` is no more implicitly exposed as `pickle.re`.

Add the following methods:
* assertHasAttr() and assertNotHasAttr()
* assertIsSubclass() and assertNotIsSubclass()
* assertStartsWith() and assertNotStartsWith()
* assertEndsWith() and assertNotEndsWith()
Also improve error messages for assertIsInstance() and
assertNotIsInstance().
We introduce a private constructor `UUID._from_int()` for RFC 4122/9562 UUIDs,
which takes the integral UUID value as input. The latter must have correctly set
its variant and version bits. We also make `UUID.__init__()` slightly more efficient.
Replaces the trampoline mechanism in Emscripten with an implementation that uses a
recently added feature of wasm-gc instead of JS type reflection, when that feature is
available.
* ssl: Add hex error code to "unknown error" messages
To make it easier to vary the individual parts of the message,
replace the if-ladder with constant format strings by building
the string piece-wise with PyUnicodeWriter.
Use "unknown error (0x%x)" rather than just "unknown error" if we
can't get a better error message. (Hex makes sense as the error
includes two packed parts.)
Fix `Lib/_pyrepl/windows_console.py` to support more keybindings, like the
`Ctrl`+`←` and `Ctrl`+`→` word-skipping keybindings and those with meta (i.e. Alt),
e.g. to `kill-word` or `backward-kill-word`.
Specifics: if Ctrl is pressed, emit "ctrl left" and "ctrl right" instead of just "left" or
"right," and if Meta/Alt is pressed, emit the special key code for meta before
emitting the other key that was pressed.
