I can't understand why the final comparison in the code below returns false.
XOpts.field is a reference, so passing it somewhere shouldn't change really
change what addr returns. At least that's my assumption, but I'm obviously
missing something here. I would be grateful if someone could clue me in.
```nim
type
XObj* = object
val*: tuple[a, b: string]
XObjRef* = ref XObj
XOpts* = object
field: XObjRef
proc return_xobjref(opts: XOpts): XObjRef =
return opts.field
when is_main_module:
var xobjref: XObjRef
new(xobjref)
xobjref.val = ("a", "b")
var opts: XOpts
opts.field = xobjref
var result = return_xobjref(opts)
echo "IS IT THE SAME? ", (addr xobjref) == (addr result)
```
