I'm not so sure about that. I was very enthusiastic about defining an 
infrastructure of arbitary-dimensional arrays, and did a little research 
about it. It turns out the applicability of N-dimensional arrays falls 
off a cliff when N > 3. In turn, this is because high-dimensional space 
are weird - an N-dimensional space is not just like a 3-dimensional one, 
only with more dimensions; it's a downright weird beast.
