[racket-dev] Should BSL signal an error on (require ...) in an unsaved buffer?

My guess about how this works--correct me if I'm wrong--is that for unsaved buffers, DrR sets a parameter such that the expanded code has the current directory as (uh, part of?) the syntax-source of the expanded source.  I'm guessing that I'm not right, or it would be as simple as disabling this for programs written in BSL et al.

In particular, my experiments suggest that "require" in an unsaved buffer implicitly requires things from (current-directory). Is this the right behavior? It would seem to me that we'd be better off signaling an error in this case.  No?
