Public bug reported:

code:

----------------------------------------
test = True
if False:
    del(test)
assert(test)
----------------------------------------

pyflakes complains:
[...].py:4: undefined name 'test'


i guess this may be too hard for a static analysier, in which case, how about

----------------------------------------
test = True
if False:
    del(test)
else:
    assert(test)
----------------------------------------

where the usage is in a different else branch to the del

output:
[...].py:5: undefined name 'test'
