Well, in my defense, I did ask a pretty narrow question, "Is id

Yes for 2.x, guaranteed no for 3.x.
If you had simply asked "Is the loop variable of a list comprehension
guaranteed to be in scope after the list comprehension?", without a
distracting example, that is the answer you would have received.
I intend(ed) to inform, not attack, hence no 'defense' needed.
While I will
admit that not knowing whether I could alter the exception, or
whether id masked a builtin or not does complexify answering some
questions, those are questions I didn't ask :-)
Except that it bears on the question you did ask because it means that
the code will run in 3.x but with different results, whereas a random
name will fail in 3.x with a NameError.
