For code this short, it is better to include it in the post, rather
than putting on a website; that makes it easier to refer to in replies.

You're welcome - gratitude is appreciated :).

Well, you can, but importing won't make sense; the pointers will not
be valid.

You don't need another type, just modify Save to not output the
pointer. 

Then in Restore (which you don't show), you need to rebuild the linked
data structure. That is the hard part; how does Restore know what
objects are linked? Typically Save must output some object ID, which
is _not_ the pointer.
