You can also call set without any arguments to add a list of all of the shell's currently set variables - also quoted for reentry to the shell. And you can - in bash - additionally add the command typeset -fp to also include all currently declared shell functions. You can lump it all together and eval when ready. You can even call alias without arguments for more of the same. That... might cover it, though. I guess there is "$@" - which you'd have to put in a bash array first, I suppose, before doing set.
