Hi Jeroen, to give a little bit background, as a student of computersciences I happen to work with bitshift not as a means of having a "quick" multiplication or division, but as using it to "manipulate" bit-patterns. The distinction between signed and unsigned rightshift is nothing strange, obscure or redundant, but is implemented down to the machine-language itsself (dependent on cpu-architecture). So this is no "bad operator", but one of the most crucial operators on bit-patterns. I don't want to sound arrogant (saying this is almost always a sure sign, that it will ;-) ) but maybe you should inform yourself the next time why other languages have this operator implemented. Disabling signed shifting will force me to turn back to perl, as I use this feature for quick hacking certain scripts I use at the University (and that would be a very cruel thing to do :o) ) - besides, it would disregard the "holy BC"...

In what case (when not dividing) do you use this kind of shift? Andi
