Provides the widen type of a singleton type.
Type member
Outof an implicitly availableWitness[T]instance is the widen type ofT, and theapplymethod explicitly converts aTto anOut.E.g. if
TisWitness.2,OutInt.It somehow complements
Witness, providing the corresponding non-witnessed standard type, if any.Example of use, {{ val w = Widen[Witness.
2.T] // w.Out is Int // w(2) is typed as Int }}
