Comment(by eric_niebler):

 I understand your point, but I still disagree. I'm not going to get into
 guessing what a "better" type to hold the result is. It can be argued from
 the other side ... that using an int to hold the result of an
 (int*unsigned) can overflow and wrap. There is no good solution. Following
 the rules of C++ is simply the best (as in least surprising, easiest to
 explain) thing to do.
