Classmethods are useful when data stored in specific instances are *not*
needed.

* Update code after merge review from 1st1

* Use a sentinel approach for loop parameter
Remove unnecessary _get_running_loop patching

* Use more clear function name (_verify_parameter_is_marker -> _verify_no_loop)

* Add init method to _LoopBoundMixin to check that loop param wasn't used

Reduce memory footprint and improve performance of loading modules having many func annotations.

  >>> sys.getsizeof({"a":"int","b":"int","return":"int"})
  232
  >>> sys.getsizeof(("a","int","b","int","return","int"))
  88

The tuple is converted into dict on the fly when `func.__annotations__` is accessed first.

It probably helped a lot a while back, but may not be as usefull
today.  We'll continue monitoring it before deletion, so true
positives can be migrated to rstlint.

The Py_TRASHCAN_BEGIN macro no longer accesses PyTypeObject attributes,
but now can get the condition by calling the new private
_PyTrash_cond() function which hides implementation details.

The smelly.py script now also checks the Python dynamic library and
extension modules, not only the Python static library. Make also the
script more verbose: explain what it does.

The GitHub Action job now builds Python with the libpython dynamic
library.

This commit also fixes up some of the overlapping documentation changed
in bpo-35498, which added support for indexing with slices.

Fixes bpo-21041.

… small containers (GH-22120)

The function accepts now the representation of the default state as
empty sequence (as returned by Style.map()).
The structure of the result is now the same on all platform
and does not depend on the value of wantobjects.

* Speed up comparison of bytes objects with non-bytes objects when
  option -b is specified.
* Speed up comparison of bytarray objects with non-buffer object.

Removing 'evaluate' makes it more consistent with other assertX entries.

On macOS system provided libraries are in a shared library cache
and not at their usual location. This PR teaches distutils to search
in the SDK, even if there was no "-sysroot" argument in
the compiler flags.

…cOS (GH-23293)

Building on older versions, and in particular macOS 10.9 still use
Tk 8.6.8 because of build problems on that version of macOS.

As [bpo-38443]() says the error message from configure when specifying --enable-universalsdk with a set of architectures that is not supported by the compiler is not very helpful.   This PR explicitly checks if the compiler works and bails out if it doesn't.
