as important is the observation that you don't necessarily have to join 
string lists; if the data ends up being sent over a wire or written to 
disk, you might as well skip the join step, and work directly from the list.

(it's no accident that ET has grown "tostringlist" and "fromstringlist" 
functions, for example ;-)
