Ben Kietzman commented on ARROW-9006:
-------------------------------------
[~wesm][~apitrou] the main difficulty I see is how best to use functionality
from the {{arrow::compute::}} in {{arrow::}}; for example Scalar::Parse might
be called when {{ARROW_COMPUTE=OFF}}. Perhaps these methods could just be
deprecated? AFAICT they are only consumed in {{arrow::dataset::}} and
{{pa.CScalar}} which already depend on the compute module.
> [C++] Use Cast kernels to implement Scalar::Parse and Scalar::CastTo

> We should not maintain distinct (and possibly differently behaving)
> implementations of elementwise array casting and scalar casting. The new
> kernels framework provides for relatively easily generating kernels that can
> process arrays or scalars.
