My question for the group is whether it would be a good idea to drop the new restriction.
I like the restriction and would actually advocate having it for regular for-loops too (though that would be a big no-no, I guess). Here's why I never use them without parenthesis, in python 2:
(1 if True else 3, 4) (1, 4) (lambda x: x * x, 6) (
, 6) [i for i in 2, 3] [2, 3] (i for i in 2, 3) File "<stdin>", line 1 (i for i in 2, 3) ^ SyntaxError: invalid syntax
And in Python 3:
(1 if True else 3, 4) (1, 4) (lambda x: x * x, 6) (
, 6) [i for i in 2, 3] File "<stdin>", line 1 [i for i in 2, 3] ^ SyntaxError: invalid syntax (i for i in 2, 3) File "<stdin>", line 1 (i for i in 2, 3) ^ SyntaxError: invalid syntax
