What did you do?

struct Window{
mut:
	widgets []Widget
}

struct Widget{
mut:
	parent &Window = voidptr(0)
}

fn main(){
	mut window := &Window{}

	mut btn := &Widget{}
	btn.parent = window

	window.widgets << btn

	dump(window)
}

What did you expect to see?
If a field refers to the struct itself, there is no need to print it.
