You get the error because "a.n" is a completely different variable
than "n"... "a" is its own namespace. To do this kind of dynamic
stuff, you either need a little routine called getattr(), direct
access to a.__dict__, or to use exec/eval.... despite what they tell
you, ThereIsMoreThanOneWayToDoIt.. :)
