  4. def apply(k: Witness)(implicit selector: Selector[C, T]): Out

    Returns the value associated with the singleton typed key k.

    Returns the value associated with the singleton typed key k. Only available if this union has a field with with keyType equal to the singleton type k.T.

    Note that this can creates a bogus ambiguity with CoproductOps#apply as described in https://issues.scala-lang.org/browse/SI-5142. If this method is accessible the conflict can be worked around by using CoproductOps#at instead of CoproductOps#apply.
