That "someone" was Grant Roberts; probably his Masters thesis is still
available from the University of Waterloo (I read the thesis some years ago;
it appeared to give a fast implementation using very different techniques
from those used at Edinburgh).  It's a pity that Grant Robert's work has
languished in obscurity because he picked the wrong target hardware.
