final class MacroGenerated[C, T] extends AnyVal

Wrapper class for macro-generated typeclasses. Usually, a typeclass is wrapped in MacroGenerated when it's accepted as implicit super constructor parameter of some base class for companion objects of types for which the typeclass is being generated. Example: HasGenCodec, which is a base class for companion objects of classes that want GenCodec to be macro-generated for them.

Instead of materializing the type class instance directly, a function from some base companion type C is materialized. To obtain the actual typeclass instance, companion object must be passed as this function's argument. This serves two purposes:

- contents of C will be wildcard-imported into macro-materialization, allowing injection of additional implicits - working around too strict Scala validation of super constructor arguments: https://github.com/scala/bug/issues/7666
