For instance you can set manually such a subscription: `namere::`. The namespace - default, the value is an empty string. Won't crash anything, but it doesn't make any sense to have it. https://codereview.appspot.com/11248043/diff/1/MoinMoin/storage/middleware/va...

Just returning True or False.

It would even match everything. https://codereview.appspot.com/11248043/diff/6001/MoinMoin/storage/middleware...

I read http://www.python.org/dev/peps/pep-0008/ and no specific guides on how to check if a value is in an iterable, tuple formatting, list vs tuple usages. My best guess is to use a set instead of a list or tuple. if keyword in {keys.NAME, }. But didn't find anything on that too. What should it look like?

Based on your example it is: if keyword in (keys.ITEMID, ): Should it become (keys.ITEMID,)?

We all need to agree on a single style.

What does mean then a separate change? New code review? Patch? Commit? Please be more specific. I have fixed it in a separate patch: #5 https://codereview.appspot.com/11248043/diff2/8002:19001/MoinMoin/storage/mid...
