DerivedExpressionDsl

@ExperimentalWowApi

class DerivedExpressionDsl

The expression context of AggregationQueryDsl.derived: constant returns a DerivedExpression.Constant rather than the AggregationExpression.Constant of AggregationQueryDsl.constant, so the two scopes do not share a receiver type.
