No formal language I know is in any significant
sense a subset of a natural language. (I don't
consider the facts that both are languages,
and one is smaller than the other, to be
significant.) There again, of course, my hand
*is* different from my body -- I'd have difficulty
in buying a jacket to fit it! :-)
