I would absolutely love to have unsigned comparison operators in 
D. Do you agree? What on earth would the syntax be like?

Yes, I could write a generic function or something, but the 
result would look ugly. And I would have to be very careful not 
to screw up type conversions (although i’m pretty sure there is 
some help available in the rtl to assist in getting the job done 
safely).

I have a hard time imagining a use case.

The reason why he have signed shift in the first place is to make 
the (n >> m) be equivalent to n * (2^^m)

It just came up in a real application. It was a case of 
bit-twiddling, happened to come up during some weird 'arithmetic' 
when trying to write a jump-free replacement expression for a ? : 
because the compiler still generated jumps for a ? : when I 
didn't want it to. (A jump-less attempt at Bresenham's line 
algorithm.)
