   Oh, I see
   
   ```python
   In [14]: b = None
   
   In [15]: a == b
   Out[15]: False
   
   In [16]: import pyarrow.compute as pc
   
   In [17]: pc.equal(a,b)
   Out[17]: 
   <pyarrow.lib.BooleanArray object at 0x12eb27340>
   [
     null,
     null,
     null
   ]
   
   In [18]: bool(pc.equal(a,b))
   Out[18]: True
   
   In [19]: bool(a == b)
   Out[19]: False
   ```
   
   I think the first option of not falling back to the length of the array (the 
NumPy "way") is cleaner though I don't really see the huge cost and annoyance 
that might bring (only slight :) ). The other option, which is changing 
`equals` and keeping `__eq__` as is, would also be OK with me, if we see the 
need to be less disruptive.
