Failing test with PyPy 3,.9-v7.3.13 on Windows.
3,9-v7.3.13 was released Sept 29 and seems to have made it into azure.
See https://dev.azure.com/numpy/numpy/_build/results?buildId=32240&view=logs&jobId=95a72139-892c-5f80-4f09-2f9a3201b7ef for the error.
The error message is:
> assert_equal(arr_method(obj), NotImplemented, err_msg)
E TypeError: operand 'MyType' does not support ufuncs (__array_ufunc__=None)
Looks like PyPy is failing to return NotImplemented.
