Actually, I ran the code you provided, which only ran against the
standalone function. I tried it just now against the class, and it
worked fine. However, that said, I did find a subtle bug: More than one
space between the '@param' and the typehint ('int' in this case) caused
the server to fail. That's easily fixed however, and I'll put an issue
in the tracker for it.
