Hi Levente,

I had not checked the 64-bit image yet, thanks. I did notice from the
32-bit image that the DateAndTime>>= test shows that we might have an
opportunity to improve #digitCompare: performance, or maybe think of
a better way to do the #= implementation. Your 64-bit results show that
it is not a problem for the 64-bit image (because we would be dealing
with immediate small integers there).

It's interesting to see that Spur is speeding up overall performance
to the point that some primitives are starting to appear relatively
slow in comparison. That is very nice problem to have :-)

Dave
