hi, thanks, that explains a lot ... 

is the referencing to this list 'uni-' or 'bidirectional'? 

when i think about it ... it's a clear advantage as long as it doesn't become a
killer, and will become a killer once it's grown too big ... thus dangerous for
big sheets / projects

is it possible / a good idea to implement it similar to linux hardlinks in
filesystems, track referencing items and require the referencers to delete the
reference as soon as it is no longer needed, or to check from the list whether
the referencing objects are still 'alive'? and release the referenced string
once all referencers are dead ... ?
