Interesting mistake. It's supposed to be `continue`. 
I actually thought it was valid but just something I hadn't heard of. The code will work. Ie. this will work:
```python
def names():
    for x in list('abc'):
        if x == 'b':
            next
        yield x
print list(names())
```
but it prints out `['a', 'b', 'c']`.
