Unfortunately, it's somewhat common for example code in various places
to show the above usage (where somebody did a "from <whatever> import
*).  IIRC there used to be examples like that even in the official
docs, but I haven't seen any there in a while.

But examples that look like that are still pretty easy to stumble
across using Google.

I'm guessing he copied the code from a "tutorial" example like this:
