dotty seq mapping to union
Clash Royale CLAN TAG #URR8PPP dotty seq mapping to union I cant get the following code to compile with the latest dotty (0.9.0-RC1), and at first glance it looks like it should... object UnionMapping { private def parse(string: String): Int | Double = { if(string.contains(".")) string.toDouble else string.toInt } def test_number = { val strings: Seq[String] = Seq("123, 2.0, 42") // Works val asdf: Seq[AnyVal] = strings.map(parse(_)) // Fails to compile val union: Seq[Int | Double] = strings.map(parse(_)) } } does anyone have any insight into why its failing and whether its expected to work?
