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.
