Content 
The problem is that you can't unpickle a data that contains both datetime 
classes (datetime, date, time) instances and strings (including attribute 
names, so actually this affects instances of any Python classes). Yes, it only 
affects pickles transferred between 2.x and 3.x Pythons.

Yet one possible solution is to change datetime classes in 2.x to produce more 
portable pickles. But new pickles will be larger, and pickling and unpickling 
will be slower, and this doesn't solve a problem with existing pickled data. 
We still are receiving bug reports for 2.7.3 and like.
