Such types can participate in value classes, but instances
cannot appear in singleton types or in reference comparisons.

found : Object
required: AnyVal
Note that implicit conversions are not applicable because they are ambiguous:
both method ArrowAssoc in object Predef of type [A](self: A)ArrowAssoc[A]
and method Ensuring in object Predef of type [A](self: A)Ensuring[A]
are possible conversion functions from Object to AnyVal
