This, and previous FB APIs, seem to really be lacking. For a Python API, for instance, you shouldn't be calling generic 'graph' functions and then passing strings to tell it what to do. If you want to do that, you might as well just construct the URL yourself.

Python is powerful for hackers because of introspection. You can pull up a shell and all of the documentation is available with type() and dir() and iPython's tricks. An API that takes actions as strings fails for Python.
