I have to assume that you meant FOO to be a hash... tho an array will
work here... sorta.

But rather than either an array or hash, what if you could write:

  FOO=Cache.new

That is, FOO would behave mostly like a hash, but unused entries would
age out after a while. Now if only someone would invent an appropriate
Cache class.
