A few tests:

```python
Python 2.7.6 (default, Apr  9 2014, 11:48:52) 
[GCC 4.2.1 Compatible Apple LLVM 5.1 (clang-503.0.38)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> assert 1, None
>>> assert (1, None)
<stdin>:1: SyntaxWarning: assertion is always true, perhaps remove parentheses?
>>> assert 1, None
>>> assert None
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AssertionError
```

So I'm concerned that this change does nothing :p
