However, the other srfi's ar *additions* to the standard.  Thus a Scheme
implementor can implement a srfi by just providing the new functionality,
and a Scheme programmer can use a srfi (if available in their
implementation) by just using its functionality.  If you define
something that conflicts with RnRS or some other srfi, things become
hairier for both the implementor and the user.

But there is no standard module mechanism (yet), except for "load"
so I don't know what "import" means.  There is srfi-7, but that
is rather a big jump for people, since "the configuration language
is entirely distinct from Scheme."
