Hi Linus,
There already exist a page in the manual about "Incompatibilities with
the R7RS" [1]. Perhaps a paragraph similar to that found in the R6RS
incompatibilities page should be added to the R7RS incompatibilities
page. Something like this:
"Multiple @code{define-library} forms in one file are not yet supported.
This is because the expansion of @code{define-library} sets the current
module, but does not restore it. This is a bug."
