Compares two aggregation values and returns true if they are equivalent.

Example

class Product(
    val name: String,
    val creationDate: Instant,
    val releaseDate: Instant,
)

val releasedOnCreation = collection.aggregate()
    .match {
        expr {
            Product::creationDate eq Product::releaseDate
        }
    }
    .toList()
