Using enum can be very useful, but I wouldn't use it for AAs at all, and I'd 
be leery of using it for much in the way of arrays other than string literals 
(since the string literals should avoid the memory allocations that other 
array literals get). It's fine most other stuff, but for those items, you need 
to be very wary of it or risk lots of unnecessary GC allocations.
