False positive "undefined name" in comprehensions

[Micro Alex]

$ cat test.py
print list(
    map(
        lambda x: '{} {}'.format(var, x),
        ['orange', 'apple']
    )
    for var in ['an', 'example']
)

$ pyflakes test.py
test.py:3: undefined name 'var'

the variable "var" is available in the lambda expression, so I believe this is a false positive for "undefined name" error.

Edit:
sorry, this was my fault, after I updated pyflakes to the latest version, the issue has gone.
