New submission from Ariel Bruner:
The following code gives a NameError:
>>> def foo(bar):
print {eval(x) for x in ['bar']}
>>> foo(2)
Traceback (most recent call last):
File "<pyshell#52>", line 1, in <module>
foo(2)
File "<pyshell#51>", line 2, in foo
print {eval(x) for x in ['bar']}
File "<pyshell#51>", line 2, in <setcomp>
print {eval(x) for x in ['bar']}
File "<string>", line 1, in <module>
NameError: name 'bar' is not defined
I've seen this kind of bug reported for Python 3.X (e.g. Issue5242), and the
behavior seems to be identical (e.g. can be fixed with {eval(x) for x in
['bar'] if True or bar}), but the previously reported bug reports mention
comprehension is implemented differently on 2.X and that it should not happen
there, so I thought that might be of interest.
