Following code compiles fine in Scala 2, but does not in Scala 3:
import com.softwaremill.quicklens._
case class State(inside: Boolean)(implicit d: Double)
def f(state: State, value: Boolean): Unit = {
implicit val dd: Double = 0
state
.modify(_.inside)
.setTo(value)
}
Error is:
State has no member named copy$default$2
