Hi,

I might understand why this does not work, but I am not convinced it
should not - following:

def nnn():
    print 'inside'
    yield 1

def nn():
    def _nn():
        print 'inside'
        yield 1

    print 'before'
    _nn()
    print 'after'


for i in nnn():
    print i

for i in nn():
    print i



gives results:

$ python f.py
inside
1
before
after
Traceback (most recent call last):
  File "f.py", line 18, in ?
    for i in nn():
TypeError: iteration over non-sequence

while I would expect:
$ python f.py
inside
1
before
inside
1
after

Any insight?

andy
