Performance Question about service instnace : getInstance(i Injector) (T, error)

[kcmvp]

func (s *serviceEager[T]) getInstance(i Injector) (T, error) {
	frame, ok := stacktrace.NewFrameFromCaller()
	if ok {
		s.mu.Lock()
		s.invokationFrames = append(s.invokationFrames, frame) // @TODO: potential memory leak
		s.mu.Unlock()
	}

	return s.instance, nil
}

above code is from https://github.com/samber/do/blob/v2-%F0%9F%9A%80/service_eager.go,

right now I am using do by generate a global singleton scope and get the service on demand. but there is a call to get call
stack everytime I try to get the instnace
frame, ok := stacktrace.NewFrameFromCaller(), in fact this methos is not exported just for internal usagae. It will decrease the system performance. is there way to optimize the design?

3 ideas come to my mind:

• add a parameter in the root scope
• add a parameter globally in the lib (eg: do.TraceInvocation = true)
• enable only if a debugging library is loaded (like github.com/samber/do/http/gin/v2)

I'm adding this to v2.1 roadmap.
