I can cythonize this code:
def test():
sentinal = '3'
with open('foo.txt', 'w') as f:
sentinal == '1' or sentinal == '2'
or this:
def test():
sentinal = '3'
with open('foo.txt', 'w') as f:
pass
sentinal in ('1', '2')
but not this:
def test():
sentinal = '3'
with open('foo.txt', 'w') as f:
sentinal in ('1', '2')
$ cython test_open.pyx
Error converting Pyrex file to C:
