This is actually an undocumented and not future-proof way of getting
static variables.  The "glitches" that make it work are described in
[1].  There was also an entry about this on of the p5p digests, but the
original site[2] doesn't seem to have it anymore -- probably to not
further publicize the trick.  Anyway, the Google cache[3] still has it.
