    Description

      A metafunction is a function that provides the Execute API but does not contain any kernels. Such functions can also handle non-Array/Scalar inputs like RecordBatch or Table.

      This will enable bindings to invoke such functions (like take, filter) like

      call_function('take', [table, indices])
