I'm puzzled as to what the problem really is from a practical point  of 
view.  Easy enough to create a 'safe' name, no?  I suppose for  tidiness 
sake one might not want variables specific to only one function to be 
global, but there's zillions of that sort of variable already so one 
lives with that rather easily. And this is universal across all shells, 
yes?  I have a set of local variables that I need to survive reboot, so 
I write 'em to a file which is reread on startup.  That would work for 
Budi, but again it seems like there's not really a big problem.  (Mind, 
I have a long history of seeing problems where there is no problem ;-)
