Using Generators Directly in Effect Service Methods

class MyService extends Effect.Service<MyService>()(
  "MyService",
  {
    effect: Effect.gen(function*() {
      const terminal = yield* Terminal.Terminal

      return {

          yield* terminal.display(`Hello, ${name}`)
        }
      }
    }
  }
) {}

      }
    }
  }
) {}
