The `possibly undefined' warnings about the srfi-9 gnu, srfi-26 and curried-definition modules are a bit unfortunate, but easy to check. It allowed me to trim quite some imports in Dezyne modules. Very nice! It seems that only re-exporting a (non-macro) variable from an otherwise un used module gives a false positive `unused module' warning; it doesn't even say `possibly unused module'. Not a big problem, but can anything be done about that?
