I think it's always been possible to do &= with Query objects because the 
__and__ method is defined. What was recently added was __rand__ and 
__ror__, which according to 
http://docs.python.org/2/reference/datamodel.html#emulating-numeric-types 
allows 
binary operations with swapped operands. So, if you have A & B, and A 
doesn't implement the __and__ method but B implements the __rand__ method, 
then it will execute B.__rand__(A). Not sure what the use case is for 
queries, though.
