Suggestion for a more schematic Effect.Service builder method or Effect.fnSet

class MyService extends Effect.Service<MyService>()("MyService", {
  effect: Effect.gen(function* () {
    // ...

    return {
      foo: Effect.fn(`${spanPrefix}.foo`)(function* (args: never) {}),
      bar: Effect.fn(`${spanPrefix}.bar`)(function* (args: never) {}),
      // ...
    };
  }),
}) {}
