It was something completely different (special handling of primitives),
and I think I have it fixed now.

I'm waiting for the next bug. But basically, this thing is getting
better and better. I really recommend everybody to give it a try.
Programming with modules catches many unbound-variable
errors and missing library uses, allows to use shorter names and one
can finally code
extensively with macros, without having to worry about compile-time/
run-time issues (well, with a batch-compiler there will always
be situations where one has to be aware of the separation,
but this is vastly better than fiddling with `syntax' and
`require-at-runtime' setup-options).
