D has operator >>> which means "unsigned shift to the right", inherited

Should we yank operator>>>?

Yes. It's an operation that doesn't make much sense -- it operates on
raw bits, not on integers. It's tied to a twos-complement
representation, and not to mathematics. If you ever try to implement >>>
for bigints, you find out how wierd it is.
I guess in the Java case, x>>>1 is cast(int)((cast(uint)x)>>1)
and there's no other way of doing it in a language which had no unsigned
types.
It had some merit before D had templates. Now, I don't think it has much
use.
