Um. Well, the arg is not a TupleTableSlot * anymore, so this is
guaranteed to fail. This isn't part of what I thought the documented
SRF API was though. If you take the arg[i] value and pass it to
GetAttributeByName or GetAttributeByNum it will work (with some compiler
warnings) and AFAICS we never documented more than that.
