Can't define value class's value as implicit

[scabug]

Seems you can't define a value class's value as implicit:

class IntW(implicit val n: Int) extends AnyVal

---

Foo.scala:1: error: value class may not be a member of another class
class Foo(implicit val n: Int) extends AnyVal
      ^
one error found

The use of Int here as an implicit class is just for reproduction purpose, it wouldn't be wise to do so.

The current workaround is to drop the implicit and define an implicit method:

class IntW(val n: Int) extends AnyVal {
  private implicit def implicitInt: Int = n 
}

The error is now

scala> class IntW(implicit val n: Int) extends AnyVal
<console>:11: error: value class needs to have exactly one val parameter
       class IntW(implicit val n: Int) extends AnyVal
             ^
