Hi,
Currently, building a wheel packaging on Python 3.10 fails with:
AssertionError: would build wheel with unsupported tag ('cp310',
'cp310', 'linux_x86_64')
This bug is discussed in many places:
* PEP 641 -- Using an underscore in the version portion of Python 3.10
compatibility tags
https://www.python.org/dev/peps/pep-0641/
* PEP 641 discussion:
https://discuss.python.org/t/pep-641-using-an-underscore-in-the-version-portion-of-python-3-10-compatibility-tags/5513
* CPython PR 20333: "bpo-40747: Make py_version_nodot 3_10 not 310"
https://github.com/python/cpython/pull/20333
* wheel: "Fails to build wheel for Python 3.10"
https://github.com/pypa/wheel/issues/354
* python3-setuptools: "python-setuptools fails to build with Python
3.10: AssertionError: would build wheel with unsupported tag ('cp310',
'cp310', 'linux_x86_64')"

> PEP 612 -- Parameter Specification Variables
> PEP 626 -- Precise line numbers for debugging and other tools.
