So is date2 now broken with 1.5.4?

Perhaps we need a method .modulo.

The problem then is with .divmod. If that returns a modulo, rather
than a remainder, then the q*y+r = x relation is broken. So then maybe 
we'd need to add .divrem too...

And so it goes. All this a day before the 16 freeze too.

If this change has broken existing libraries, my vote would be to
revert to the old behavior and let's dicuss this some more for 1.8.
