Executing this fails:
class Data:
foo = 12
bar = 42
baz = [i * bar for i in range(foo)]
Executing this works:
foo = 12
bar = 42
baz = [i * bar for i in range(foo)]
I found this question which seems to be a more complicated version of essentially the same problem, but no clear answer to why the scope seems to change within a class + dict / list comprehension.
