Two ideas occur to me:
* make the list comprehension a new scoping level, which of course
is doable now that we have sensible scoping semantics. Presumably
the usual warning message about shadowing variables from an
outer scope will apply; you'll still have the bug in your code,
but at least Python will tell you about it
* don't make list comprehensions a separate scope, but add a
little trickery so that something *like* the "shadowing variable
from an outer scope" message is emitted
Haven't really thought about backwards compatibility issues...
