Destructor not called for ref object

[juando]

Hi I am new to this language so please bear with me. I was trying to create a 
simple example with refs and destructors.

Here is the code:
    
    
    type
        MyObj = object of RootObj
            name: string
        MyObjRef = ref MyObj
    
    proc `=destroy`(obj: var MyObj) =
        echo "Destructor called for ", obj.name
    
    #[
    proc finalizer(obj: MyObjRef) =
      echo "Finalizer called for ", obj.name
    ]#
    
    proc newMyObj(name: string): MyObjRef =
        let r = new(MyObjRef)
        r.name = name
        return r
        #[
        new result, finalizer
        result.name = name
        ]#
    
    proc myfunc() =
        var o1 = newMyObj("Obj1")
        var o2 = MyObj(name: "Obj2")
        echo o1.name, " is ready"
        echo o2.name, " is ready"
    
    when isMainModule:
        myfunc()
    
    
    Run

I have also tried with finalizer (see commented code), but no matter what I do, 
the result I get is:
    
    
    Obj1 is ready
    Obj2 is ready
    Destructor called for Obj2
    
    
    Run

I have tried both with and without '\--newruntime' flag, but the results are 
the same. The destructor (or finalizer) is not called for reference object. I 
even tried calling `GC_fullCollect()`, but did not work. What am I doing wrong?
