It's actually masking, not reassigning. That may make it easier or
harder to resolve the issue.
If you want a future directive that deals with it, I'd do it the other
way - from __future__ import mask_builtin_warning or something - so
the default remains as it currently is. But this may be a better job
for a linting script.
