Hi Graham,
If you do want a deep copy of a collection, check out <http://developer.apple.com/documentation/CoreFoundation/Reference/CFPropertyListRef/Reference/reference.html#//apple_ref/c/func/CFPropertyListCreateDeepCopy
>. NSPropertyListSerialization would be the Cocoa equivalent of this
API.

Does anyone know whether methods such as:
[NSArray initWithArray:<someArray> copyItems:YES];
continue to deep-copy items for further collections within the root
collection, or do they fall back to a shallow copy (retaining)?
If no-one knows I can spend an hour or two doing some experiments
but if
it's just a known 'yes' or 'no' I'd rather save the time!
It will send the -copy method to each of the items in the array, and
insert the resulting copies into the new array.
So, context specific. If the items are Cocoa collections, that means
shallow copies of items.
