So in the example above, where both annotated and aggregated kwargs are
named `foo`, the output should actually contain just the last one, right?
The first annotated `foo` column can just be renamed and then removed from
the final result (to avoid confusion). That would be accesptable solution
without large rewriting of the code I hope.
