Good question. The fact is that Numeric, numarray and scipy_core has
all been designed to support objects up to 32 (and perhaps 40 in some
cases) dimensions. Why? I must confess that I don't exactly know, but
when your mission is to check every bit of the implementation and push
your package to its limits, you may encounter very funny things that
probably will never be a problem for real users.
Somehow, this kind of issues with high dimensionalities are sometimes
useful for isolating other potential problems. So, yeah, one can say
that they are usally a loss of time, but sometimes they can save your
life (well, kind of ;-).
