Feature or enhancement

Extend the datetime.date class with a new method timestamp() that mimic the same behavior of datetime.datetime.timestamp, where the time is implicitly "00:00".

Pitch

At the moment both datetime.datetime and datetime.date offers the fromtimestamp() classmethod to convert from float.
datetime.datetime objects, moreover, offer the timestamp() method to convert to float.
A similar method lacks for datetime.date.

Apart from the (lack of) symmetry, there are also some use cases where it's necessary to switch back-and-forth between datetime.dates and floats and it would be handy to have some predefined function already.
