Comment:

 In response to Forest and mitar: let's keep this a documentation ticket as
 Malcolm suggested, and move any deep/shallow copy feature additions to a
 new ticket (and probably start a mailing list discussion to make sure we
 have consensus on the feature).

 For the time being, a ticket this old really needs some kind of
 resolution, and documenting a simple and useful pattern that covers 90% of
 cases is a good idea, even if copy methods do get implemented at a later
 date.

 I would say that either docs/topics/db/models or docs/topics/db/queries is
 probably the place to put the docs for this. Despite the fact that
 topics/db/models is a more appropriate section, it actually fits better
 context-wise with topics/db/models near the sections of updating and
 deleting objects. A case for going into either one could be made, and
 ultimately there should probably be a cross-ref from one section to the
 other whichever way one it ends up in.
