Well, yes, it starts a subshell, but that shouldn't prevent a function
in the calling shell from testing for the existence of the file before
script even gets started.

    function script {
      emulate -L zsh
      setopt noclobber
      zmodload -i zsh/zutil
      local -a opts
      zparseopts -D -a opts a c: f q t  
      set -- "${@:-typescript}"
      if [[ -e $1 ]]; then
        print -u2 script: file exists: $1
	return 1
      fi
      command script $opts $*
    }
