I did, it's much more elegant.  I've never seen generate_series used
like that, it's a very nice way of doing things.  If your arrays are
ever more than a few elements long his is probably going to be much
faster.  Generally for less than 6 or 7 elements it's better doing the
naive thing, not sure if that applies here though.
