Completely valid concerns; I thought the data bore a strong
resemblance to the desired output described in another thread
about parsing words out of a long chunk of text, so I assumed
that Louis was actually creating the original "unsorted" data
himself. Clearly the production use of an approach like the
one I posted would require that the interface and assumptions
be precisely documented, so that any change upstream could be
checked against the requirements of the downstream code.
