However, aggregate error handling says to not bind the result in case of an error. So to simplify logic in the caller, we return undefined by default.
Base implementation of putBindings, that evaluates to a term and then calls putTerm. The WildcardCountAggregator will completely discard this implementation.

This is the base class for all aggregators. NOTE: The wildcard count aggregator significantly differs from the others and overloads parts of this class.
