Issue description:

Memery leak with cyclic preload in GDScript.

Steps to reproduce:

extends SceneTree

const b = preload("b.gd")
func _init():
	quit()

Create another script b.gd with content as below

const a = preload("a.gd")

Run the script a.gd with godot

The program complains about memery leaks

This is not a bug, this is a feature. It's in the GDScript documentation. Any cycles are leaked.

So how to use this feature in right way？
I can't write as weakref(preload('b.gd')

@Geequlim you cant, simply dont do cycles. Just dont use preload, use load() normally and then you can weakref.
