Although separate compilation was a goal for the R6RS,
the actual semantics of separate compilation is not
described by the current draft.

My personal opinion is that it should cause an error
at link or load time, and that is what I intend to
implement. Since the current draft doesn't specify,
however, the behavior you observe will depend upon
your implementation.

I brought this up some time ago. IIRC, the editors
felt that binary compatibility was outside the scope
of the specification.
