MorphSlot extension for duplicate?

If a morph holds onto another morph in an instVar,
it often shouldn't be copied when doing a duplicate.
Is that something that a MorphSlot variant could support?

Hi,

The method doing the copying could take into account the type of variable used and not recurse it when copying.
In addition, with first class variables one could attach meta data for object copying and have some
annotation “skip this when duplicating”.

Pay attention that the more magic you use the more difficult to
understand the system will be.
For me duplicate should call copy and we should be able to see that copy
does not copy the instVar.
