Changing an object's field is rejected in a destructor with new syntax

[Araq]

The correct way to do it is this:
    
    
    type BObj = object
        aref: ref AObj
        name: string
    
    proc `=destroy`(x: BObj) =
        echo "Destroying B named ", x.name
        `=destroy`(x.aref)
        `=destroy`(x.name)
    
    
    
    Run

Strings must be destroyed too.
