  RecordCreated.AddListener(func(ctx context.Context, record Record) {
    fmt.Println("Record created:", record)
  }, "key1") // <- Key is optional useful for removing the listener later

  // Add a listener to the RecordUpdated signal
  RecordUpdated.AddListener(func(ctx context.Context, record Record) {
    fmt.Println("Record updated:", record)
  })

  // Add a listener to the RecordDeleted signal
  RecordDeleted.AddListener(func(ctx context.Context, record Record) {
    fmt.Println("Record deleted:", record)
  })

  ctx := context.Background()

  // Emit the RecordCreated signal
  RecordCreated.Emit(ctx, Record{ID: 1, Name: "John"})

  // Emit the RecordUpdated signal
  RecordUpdated.Emit(ctx, Record{ID: 1, Name: "John Doe"})

  // Emit the RecordDeleted signal
  RecordDeleted.Emit(ctx, Record{ID: 1, Name: "John Doe"})
