In this case, I think the right solution to the problem is two-fold:

    1) from __future__ import lexical_comprehensions

    2) If you don't import the feature, and you write a program that depends 
on
    a list-comprehension variable remaining in scope, the compiler should
    issue a diagnostic along the lines of

        Warning: This program should be taken out and shot.
