I'm already working on too many different things to take a serious run
at a labelled values proposal, but it is avoiding precisely this kind
of problem that makes me favour a permissive solution that *doesn't*
define any new behaviour for the instance, aside from changing the
result of repr() and the contents of pickles. (You could potentially
combine it with a "sensitive values" proposal that ensured repr() and
other operations only displayed the label without showing the contents
at all - this is also potentially useful for labelling large strings
that may otherwise overwhelm debug output).

Cheers,
Nick.
