The following code prints FFFF0000. Similar thing happens when
a and b are
bytes.
Is this intended?

void main()

integer operations are always promoted to at least int. That's
standard fare since C. I think it is a performance thing: Unpack
into ints, oeprate, repack into ints.
D's stance regarding integer operations is "if it compiles, it
creates the same output as in C".
It's kind of a gotcha, but not that big a deal.
