Status of Tupled Function

What is the status of Tupled Function? I don’t see any threads about TupledFunction.

Perhaps interesting for people like me who had already forgotten about this experimental feature: TupledFunction is a typeclass for tupling and untupling functions of any arity, including arities >22.

If you are interested how it can be used - I used it in scalamock like this:

github.com

ScalaMock/ScalaMock/blob/master/core/shared/src/main/scala/org/scalamock/stubs/Stubs.scala#L44C3-L170C1


      
          extension [F](inline f: F)
          
            /** Allows to set result for method without arguments.
             *  {{{
             *   trait Foo:
             *     def foo0: Int
             *
             *   val foo = stub[Foo]
             *
             *   foo.foo0.returns(5)
             *   foo.foo0 // 5
             *  }}}
             * */
            inline def returns(
              using NotGiven[TupledFunction[F, ?]]
            )(
              value: F
            ): Unit = returnsImpl[F](f, value)
          
            /**
