Finally got off my butt and hunted down an example, and it was right under
my nose in mplot3d.
lib/python2.7/site-packages/mpl_toolkits/mplot3d/axes3d.py:1094:
FutureWarning: comparison to `None` will result in an elementwise
object comparison in the future.

That being said, I do wonder about related situations where the lhs of the
equal sign might be an array, or it might be a None and you are comparing
against another numpy array. In those situations, you aren't trying to
compare against None, you are just checking if two objects are equivalent.

Hi,
I just encountered the following in my code:
FutureWarning: comparison to `None` will result in an elementwise object
comparison in the future.
I'm very concerned about this. This is a very common programming pattern (lazy
loading):
class A(object):
def __init__(self):
self._s
