uarantee that "y" = "k"^"x"
unless you use the modified table, anyway.
Bear in mind, this suggestion stems from a personal bias toward clever XOR
tricks; at that, I once wrote a set of endian-swab functions with no
(explicit) temporary variables, purely using XO
CAST ("Data" AS BLOB);
Y’know the urban legend about the folks at the restaurant who design a
complicated plan for switching the contents of salt and pepper shakers
which have their hats juxtaposed, and then a passer-by suggests just
switching the caps?
Thank you, Mr. Willoughby
