why does rawquery not support iterator
Is there a very compelling reason for using `raw()` in your case? The above could simply be written as `Article.select()`.

Raw queries *do* support iterator in 3.x:

```python

query = Article.raw('select * from article')
for article in query.iterator():
    # do something with article.
``` In 3.x raw queries support `iterator()`. Thank you.
I want to execute some codes like:
`Article.raw("select * from article").iterator()`.
However, I got:
`{AttributeError}'RawQuery' object has no attribute 'iterator'`
