 A list of Scala compiler errors that could be more helpful, especially for newcomers to Scala.
 
-The list is focused on Scala 3's Dotty compiler. One day this list could be used to help a [larger project](https://contributors.scala-lang.org/t/towards-better-error-messages-in-scalac/1470/31) around compiler errors. Such a project seems unlikely to occur for Scala 2.13's scalac, which is why this list is Dotty-specific.
