Hi Vincent

I was going through your medium article and you said a good solution would be to use the pointer and convert back to this same struct pointer.

How do we achieve this?

func emptyInterface(i interface{}) {
	s := i.(*MultipleFieldStructure)
	y := s
	x = *y
}

what should be the declaration type of y likewise in the case of var x MultipleFieldStructure

Can you please provide a complete example of this? I'm quite new and trying to get my head around.
