I'd thought along this line -- I'd even though about implementing a
stack within foo and then you could push, pop+push and pop args to and
fro -- this would do away with having to declare stuff (which the
setAttr() is really still doing) but would lead to the usual stack
management problems (as well as being hellish to understand, as you
intimated). Still and all, having i = 3 return 3 would be the nicest
for this app ..
