I think `__bool__` should return False if the given scalar is null. It's already the case for boolean scalars but it should be the case for other scalars as well: ```python >>> bool(pa.scalar(None, type=pa.bool_())) False >>> bool(pa.scalar(None, type=pa.int8())) True >>> bool(pa.scalar(None)) True ``` I also think non-null scalars should have similar boolean evaluation as the corresponding Python values: ```python >>> bool(0) False >>> bool(pa.scalar(0)) True ``` NumPy does this too: ```python >>> bool(np.int8(0)) False >>> bool(np.float16(0)) False ``` -- This is an automated message from the Apache Git Service.
