Your proposal is ambiguous. What does that mean? Can you give an example?

You mean like they already do?

>>> datetime.datetime(2008, 03, 35)  # 35th of March
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: day is out of range for month




As for ambiguous, how can datetime arguments be ambiguous?

    Help on class datetime in module datetime:

    class datetime(date)
     |  datetime(year, month, day[, hour[, minute[, second[, 
                 microsecond[,tzinfo]]]]])


What possible ambiguity is there?
