Is there any reason why arithmetic operation on shorts and bytes return int?

Simen's example doesn't seem to work though, so he appears to have found a 
bug. Certainly, I don't see anything wrong with it, but alias this doesn't 
seem to work for it. Regardless, my point was that if there's a case where 
alias this isn't doing an implicit conversion, then it's a bug, because that's 
the whole reason that it exists.
