Could you possibly just keep it as a hash?
Not refer to a and b but vars["a"] and vars["b"]?

One problem, I think, is that eval can't create a
new local variable. (It can, but only within the 
context of the eval -- it won't be defined when 
you return.)

Would it be practical to make these instance
variables, i.e., @a, @b, etc.? Or, heaven help us,
globals?
