Yeah, it is essentially what I meant, as in the first byte is the status byte.
I can change the name to `status`, but what I'd really like to know is how to
make rest arguments in WebIDL. It's currently not all so obvious what the
meaning behind data0 and dataX is, at least compared to how obvious I want it
to be. Maybe it should just be a note or something? If we have a WebIDL guru
around here, I'd appreciate the help.
