> Many of the compute kernels feature functions which accept only array inputs in addition to functions which accept Datums. The former seems implicitly like a convenience wrapper around the latter but I don't think this is explicit anywhere. Is there a preferred overload for bindings to use? Is it preferred that C++ implementers provide convenience wrappers for different permutations of argument type? (for example, Filter now provides an overload for record batch input as well as array input)
