Presumably it would maintain a list and then every time you used a
variable, it would have to check to see if it was in the list. But once
you added a variable to the list, you would never have to add it again,
which would be a nice feature. How many times have you made the error
of forgetting to declare a global variable in subsequent handlers?
Maybe I'm a bit brain-dead, but I must have made that error some 30
