I've been using my own multi-dimensional array class for years now, and 
my biggest regret is that I added support for subscripts starting at an 
arbitrary number.  This means that even though 99% of my array 
dimensions start at 0, every function that takes a multi-dimensional 
array as argument is now complicated by having to be aware of the 
possibility of a dimension starting at a different number.  That's a lot 
of additional complexity for minimal benefit.
