In scala, how to avoid class method hiding by companion object

Question

When defining Slick table projections like this:

def * = (id.?, email, human, langUser, langLearn) <> (User2.tupled, User2.unapply)

I observe that tupled method becomes invisible as soon as I define object User2.

My question is what is going on and how to avoid method hiding by companion objects.

Tupled on custom case class companions requires manually extending a function type See: https://issues.scala-lang.org/browse/SI-3664 https://issues.scala-lang.org/browse/SI-4808
