I wouldn't classify type assertion as reflection. It's a super fast type check of the object header, not dynamic reflection.

But this is a detail of implementation, user code does not use reflection with errors.

That "detail of implementation" is what is used by user code, e.g., `myError.As(...)` uses reflection, implicitly.
