This is to avoid creating a forward dependency between the two.  Also,
many people (like myself) regard `syntax-rules' as simpler to use, and
have trouble dealing with `syntax-case'.  We don't want to require
them to understand the much more complicated specification of
`syntax-case' just to be able to use `syntax-rules'.
