def _implementation():
    """Return a dict with the Python implementation and version.

    Provide both the name and the version of the Python implementation
    currently running. For example, on CPython 3.10.3 it will return
    {'name': 'CPython', 'version': '3.10.3'}.

    This function works best on CPython and PyPy: in particular, it probably
    doesn't work for Jython or IronPython. Future investigation should be done
    to work out the correct shape of the code for those platforms.
