Sure, but how do you implement, let's say, byte swapping on an integer?

ubyte[] x = &myInt[0 .. 1];
foreach(i; 0 .. x.length / 2)
    swap(x[i], x[$-i-1]);

So if the compiler can assume that x can't point at myInt, and thus 
myInt can't have changed, then we have a problem.

You just can't do this with void (or at least not very easily).
