I think that would work well if we had overloaded constructors, but 
without them it might complicate things too much. What would the 
signature look like?

Also, that would be inconsistent with how a datetime is converted to a 
date - as a user I would then expect the date constructor to take a 
datetime, too. If datetime.date() converts a datetime to a date then I 
naturally think to call date.datetime() to go the other way.
