You'd have to forbid
  local foo=bar
then.  (I guess you didn't want to use it anyway.)

Hmm, if it weren't for quoting issues, you could use
local ()
{
  for l
  do
    case $l in *=*) eval "$l";; esac
  done
}

but quoting kills that, unfortunately, and func_quote_for_eval
might be way overkill here.
