final case class Aggregate(sym: TermSymbol, from: Node, select: Node) extends BinaryNode with DefNode with Product with Serializable
An aggregation function application which is similar to a Bind(_, _, Pure(_)) where the projection contains a mapping function application. The return type is an aggregated scalar value though, not a collection.
