+The migration to the new scheme is complicated, in particular since the [kind projector](https://github.com/typelevel/kind-projector)
 compiler plugin still uses the reverse convention, with `?` meaning parameter placeholder instead of wildcard. Fortunately, kind projector has added `*` as an alternative syntax for `?`.
 
 A step-by-step migration is made possible with the following measures:

 The type class `TupleFunction` provides a way to abstract directly over a function of any arity converting it to an equivalent function that receives all arguments in a single tuple.
