Is it possible to intentionally fail at compile time?

Hey there!
Thank you for this amazing library. I have a use case in Scala 2.x where I would like to fail at compile time given some some criteria (for example, the sealed trait should not contain any case objects for its terms), do you think this it’s possible do something like this?

This is similar to throwing compile time failures during inlines in Scala 3.x

You can do it with a custom macro, which could call magnolia. So doable, but not implemented in magnolia itself :)
