Devs are aware that there is an exception to the general rule for the 'for' clause. There is a technical reason why the exception is possible, though I have forgotten it.

Since you already know that changing the general behavior has been rejected, are you asking that the exception be removed (for consistency) , so that your first example would fail? If so, that will be rejected also.

I am changing this to a doc issue in case you or someone else wishes to suggest a doc improvement.

The solution to the limitation on generator expressions, of course, is to write out the generator one is trying to abbreviate.

def clipper(max):
    for i in range(5):
        if i < max:
            yield i

class Foo:
    x = 3
    y = list(clipper(x))

print(Foo.y)
# [0, 1, 2]
