**Example**
type
Foo = ref object of RootObj
data: int
parent: Foo
proc `=destroy`(self: var type(Foo()[])) =
echo "destroy foo ", self.data
for i in self.fields: i.reset
proc getParent(self: Foo): Foo = self.parent
var foo1 = Foo(data: 1)
var foo2 = Foo(data: 2, parent: foo1)
foo2.getParent.data = 1
# output
destroy foo 2
Run
**Possible Solution 1**
proc getParent(self: Foo): lent Foo = self.parent
# output
destroy foo 2
destroy foo 1
Run
**Possible Solution 2**
var foo = foo2.getParent
foo.data = 1
# output
destroy foo 2
destroy foo 1
Run
To my understanding, lent type for ref object is meaningless, it shouldn't
change the result for the code.
