    Why does permuting with sxhash have to be one or the other of car and
    cdr?  Why can't it be both, e.g. rotate left with the car and right with
    the cdr?  (Though frankly I'd prefer something a little more drastic than
    a mere rotation.)
In the file JONL;RHSH >, you will find some routines which I have
used to experiment with various s-expression hashing algorithms.
I'f you'd like to try out some, and send me your conclusions . . .
