Yes, in this case (it wasn't my example!). But I would hope that we provide
a way of providing compact array storage where we need it. This would be
useful for lists of floats or ints that will be frequently iterated through
and directly manipulated. Image processing and statistical analysis come to
mind as obvious applications. Anyway, this is hard to discuss without an
RFC... I'm sure I've get some time to write one someone around here...
