> I was surprised to find you can't use standard arithmetic operators on PyArrow arrays and scalars. Instead, one must use the compute functions:
> {code:Python}
> import pyarrow as pa
> arr = pa.array([1, 2, 3])
> pc.add(arr, 2)
> # Doesn't work:
> # arr + 2
> # arr + pa.scalar(2)
> # arr + arr
> pc.multiply(arr, 20)
> # Doesn't work:
> # 20 * arr
> # pa.scalar(20) * arr
> {code}
> Is it intentional we don't support this?
