I believe this is not the case, I have updated example to use ordereddict, same

What exactly are you trying to demonstrate?
As explained by Benjamin, the output can differ from one invokation to another
because the iteration order depends on the hash value (position in the
buckets). Running your script on Python 2.7 or curent

No, there's a bug in your code:
nest_variables(collections.OrderedDict({'foo.bar': '1', 'foo': '2'}))

inserted in a random order.
Just use this and it'll work properly:

There's actually a parenthesis missing:

You're relying on the iteration order of dictionaries being consistent. That's
a bug in your program.
