> It has been noted by users that the [Compute Functions documentation
> ("Invoking functions" section) states that functions are invoked via
> CallFunction|https://arrow.apache.org/docs/cpp/compute.html#invoking-functions],
> but there exist functions (specifically ["Grouped
> aggregations"|#grouped-aggregations-group-by]) that can't be invoked directly
> via {{CallFunction}}. This is a bit misleading, although this is stated in
> the description of "Grouped aggregations".
> Grouped aggregations are stateful functions and at the moment stateful
> functions are not invocable in such a way.
> We should clarify in "Invoking functions" section that not all compute
> functions are directly invocable via {{CallFunction}}.
