For sure. I'm just speaking in relative terms. Scala makes it really easy to write seriously complex code and types. You end up with fun stuff like this: def

For sure. I'm just speaking in relative terms. Scala makes it really easy to write seriously complex code and types. You end up with fun stuff like this: def map[U](f: T => U): Group[U] = collect { case e => f(e) } implicit def canStackFromFac[Req, Rep] : CanStackFrom[Filter[Req, Rep, Req, Rep], ServiceFactory[Req, Rep]] = new CanStackFrom[Filter[Req, Rep, Req, Rep], ServiceFactory[Req, Rep]] { def toStackable(_role: Stack.Role, filter: Filter[Req, Rep, Req, Rep]) = new Stack.Simple[ServiceFactory[Req, Rep]] { val role = _role val description = role.name def make(next: ServiceFactory[Req, Rep])(implicit params: Params) = filter andThen next } }
