At the moment, it isn't defined particularly as either a function or a class, so all you can assume is that it is indeed a callable. The docs say that it is *roughly* equivalent to the code below it. As with most of itertools, there are a variety of edge cases that will behave oddly in the simple sample code given, but are correctly handled by the actual implementation.
