Here's one way of getting setopt to do that (a bit more neatly).

setopt() {
  if (( $# )); then
    typeset -ga global_setopt_args
    global_setopt_args=("$@")
    trap 'builtin setopt "${(@)global_setopt_args}"' EXIT
  else
    local k
    zmodload -i zsh/parameter

    for k in ${(ok)options}; do
      printf "%-20s\t%s\n" $k ${options[$k]}
    done
  fi
}

It's a little hairy because running setopt as a function is unnatural
owing to the fact that certain options (xtrace in particular) always
have function scope.  Alternatively, just use a separate function.

showoptions() {
  local k
  zmodload -i zsh/parameter

  for k in ${(ok)options}; do
    printf "%-20s\t%s\n" $k ${options[$k]}
  done
}
