The trick here would be ensuring this only applies to Python 2. Take for example the following on Python 3:

[x for x in range(3)] print(x)

You will get a NameError because x is undefined outside the list comprehension.

Note that pylint just grew a --py3k flag, which is used when scanning Python 2.x code looking for potential problems porting to Python 3.x. If pyflakes grew a similar flag, William's proposed check could be enabled only when --py3k was given. Skip
