The release documentation for gnuradio-3.9.4.0 says that it now
supports GRC with Fedora-35, but doesn't that use python-3.10?  At
any rate, although I don't use Fedora-35, I had to apply the patch
below to get any gnuradio-companion flowchart using a range widget
to work with python-3.10.0.

There seem to be type errors in range.py which are detected by
python-3.10 but not by earlier versions.  The patch fixes it for all
my uses but I can't guarantee that it covers every possible dynamic
code path.
