No, but with the change code that works in 3.5.2 could break in 3.5.1 or 
3.5.0.

It's a 2/3 compatibility issue with enum34 and aenum which support 
_order_, and Python3.4+ which does not.  The work-around is to use 
__order__ instead (or use enum34 or aenum instead ;) .

Either way, it's only similarity to a bug is I should have named it 
_order_ in the beginning, and put the compatibility shim into the stdlib 
version at the same time.
