   > the null equality tests look like a nuisance for regular Python usage (`__eq__` should return a boolean)
   
   The reason that those scalars return null on equality check and not True/False, it to ensure consistent behaviour between arrays and scalars (to ensure `(arr1 == arr2)[0]` and `arr1[0] == arr2[0]`gives the same answer). 
   Our element-wise equality propagates null, and so IMO also the scalar should do.
