Thanks for your answer. Instead of your 'always'-block, I tried
trap 'unfunction bar' EXIT - but of course this is no good in case of
name clashes :).

So, if nothing like this really works (and local functions are not been
to be implemented into zsh), I'll just use the $0_bar approach (wasn't
aware of this), to at least reduce the chance of clashes.
