```
 Function1<List<DataRow>, Long> simulateAggregation(Sum.Companion.SumAsLong<E> expression)
```
    Provides a Kotlin simulation of the given Expression as an aggregation to be applied to multiple DataRows.
    For the Expression to aggregate multiple DataRows, it must either be an rocks.frieler.kraftsql.expressions.Aggregation, one of the groupExpressions or the same must apply to all its sub-expressions.
    
    Returns:
    
    a function that simulates the Expression
