My feeling is that I'm hungry and would like to eat and you ask whether
my requirements are a sandwhich or a bowl of soup. :-)

The real requirement IMO is that any attempt to mutate an object wont
result in a mutated key. Both proposals seem to solve that. The second
is at the moment for me the most interesting to discuss, since it is
a new approach to me, and most likely to learn me something new.
