Copying the discussion between Antoine and me from python-dev:

I see your point about close(). I assume your reasoning was to make the IncrementalParser an arbitrary stream end-point. However, it doesn't really make all that much sense to connect an arbitrary data source to it, as the source wouldn't know that, in addition to passing in data, it would also have to ask for events from time to time. I mean, you could do it, but then it would just fill up the memory with parser events and loose the actual advantages of incremental parsing. So, in a way, the whole point of the class is to *not* be an arbitrary stream end-point.

Anyway, given that there isn't really the One Obvious Way to do it, maybe you should just add a docstring to the class (ahem), reference the stream protocol as the base for its API, and then rename it to IncrementalStreamParser. That would at least make it clear why it doesn't really fit with the rest of the module API (which was designed some decade before PEP 3156) and instead uses its own naming scheme.
