No inside info, other than discussions with Scott Raney on other issues 
which suggest he's very good with hashes and likes them a lot.

In this case it was just a guess based on the blazing speed of array 
access relative to any other lookup method.  I had occassion this summer 
and last to do some extensive benchmarking on various lookup methods, 
and have always found that if I can use an array I can speed things up 
by several orders of magnitude.
