    The whole thing: import scala.quoted._ inline def unpack[T <: String & Singleton]: List[Char] = ${unpack[T]} def unpack[T <: String & Singleton: Type](using Quotes) = import quotes.reflect._ TypeRepr.of[T] match case ConstantType(StringConstant(s)) => Expr(s.toList)

        Ah, I see you're returning the singleton-literal-typed tuple, and not just a boring old List[Char]!
