This PR takes into consideration the failure of Numba ufuncs in our NEP-50 aware machinery. It's unfortunate that this has taken a subsequent PR, but in retrospect we should have duck-typed this from the beginning.
Now, we just ask the ufunc object if it supports NEP-50 via
resolve_dtypes
. In future, we should gracefully support Numba's implementation, assuming that it implements this in a similar way to NumPy, which it ought to.Our test suite will fail once Numba >=0.59.0 is available, because we can't know for certain what kind of exception it will throw. Thus, we'll catch that at the time and implement the correct exception handler in pytest.
