@keyword declares the keywords you are using so that if you have used
words  which a future version of N3 defines as keywords, you won't be
and you can chose even to just deprive yourself of some keyword-based
features in order to be able to use more words.  Maybe "@" could
be generalized to force interpretation as a keyword, so @prefix becomes
an example of the general case.
