Finding FISH spots
From the Nix shell, run nox --list to see a list of available commands, notably to run tests against different versions of Python, to reformat code to be style-compliant, and to run the linter.
NB: To pass arguments through nox to pytest, separate the argument strings with --, e.g.:
nox -s tests-3.11 -- -vvto run the tests with additional verbosity (e.g., pytest -vv)
