This is necessary to fix some implicit resolution errors. Included is an implicit conversion from `K ->> V` back to `V` so in most cases it will still seem like `(K ->> V) <: V`.
…of `Remover` on right side.
This is necessary to work around what I'm assuming is a bug in the scala 3 compiler -- the following code errors when it's simply an opaque type for `V`: ```scala import typify.tuple._ import typify.record._ val t = ("s" ->> "foo") *: ("i" ->> 3) *: EmptyTuple val s = Selector[("s" ->> String) *: ("i" ->> Int) *: EmptyTuple, "i"] // java.lang.ClassCastException: class java.lang.Integer cannot be cast to class java.lang.String ```

Rewrites the majority of the shapeless-like record typeclasses in
typify.labelled
(now namespaced undertypify.record
) and adds a handful of tuple typeclasses (forHList
s in scala 2) under thetypify.tuple
namespace.There were a number of hurdles but all had workarounds:
type ->>
toopaque type ->>
opaque type ->>[K, +V]
is an alias fortypify.TranslucentTagged[V, K]
and not justV
Selector.Aux[T, K, O]
