It all depends on how important backwards compatibility with C is (I wish it weren't important).

From a machine code point of view, D's behavior probably makes more sense, at least with intel.

I know, in this case it would seem odd to rely on such behavior of C (I expect such operations are generally placed in a short and thus does not care what happens as an int)

But I do understand the desire behind the rule. I mean it is much easier to convert C when you have the compiler yelling at you.
