Looking at the original question, I'm reminded of why we've continued to
develop new programming languages.  A 'mangle' like x +=1 has nothing to
do with prolog: is 7 now equivalent to 6?  Rolling the digits on the
register object is best left to the object-oriented extensions, and I
for one would rather the compiler accepted a more logical x' = x + 1 and
spat out a terser INC AX!  Ours is not to wonder how ...
