If compact storage is the problem, ocaml 3.00 also provides bigarrays,
which allow you to store int32 values in flat arrays (even
multidimensional).
For the cost of boxing/unboxing in int32 computations, you will
probably have to test whether it meets your needs or not.
By the way, is there any plan to do for int32 the same kind of
optimizations as are done for floats (no boxing/unboxing in the middle
of a computation)? Already done?
