 In both cases, the Scala compiler automatically constructed a class manifest for the element type (first, `Int`, then `String`) and passed it to the implicit parameter of the `evenElems` method. The compiler can do that for all concrete types, but not if the argument is itself another type parameter without its class manifest. For instance, the following fails:
