New submission from Alex Mashianov <[email protected]>:
This code:
class A:
a = 1
b = {str(x): x for x in range(5) if x != a}
Produces following error:
Traceback (most recent call last):
File "<input>", line 1, in <module>
File "<input>", line 3, in A
File "<input>", line 3, in <dictcomp>
NameError: name 'a' is not defined
Which i think it shouldn't produce. Issue occurs only in dict comprehensions
inside class definitions referencing class attributes(which are in local scope
during definition).
