Usability Issue with Extracting Types from TaggedEnums in TypeScript

type _Banana = { name: string; }
type _Apple = { name: string; }

type Item = Data.TaggedEnum<{
  Apple: _Apple;
  Banana: _Banana;
  AppleAndBanana: {
    apple: _Apple;
    banana: _Banana;
  };
}>

export const Item = Data.taggedEnum<Item>()

type FromConstructor<T extends Data.Case.Constructor<any, any>> = T extends Data.Case.Constructor<infer U, any> ? U : never;

// PROBLEM: Have to extract the tagged types from the TaggedEnum
export type Apple = FromConstructor<typeof Item.Apple>
export type Banana = FromConstructor<typeof Item.Banana>
export type AppleAndBanana = FromConstructor<typeof Item.AppleAndBanana>

// PROBLEM: InnerApple is the untagged version
type InnerApple = AppleAndBanana['apple']
