At this point there is no production ready Slick version for Scala 2.11.0. Only milestone Slick version 2.1.0-M1 compiles on new Scala.
Slick Table class requires tupled & unapply methods to compile. Those methods does not exists in case classes with arity > 22
So as of April 22 2014 we still have to use HList to overcome arity limits
Thanks to @Régis Jean-Gilles who helped me to unconfuse myself
