The problem is that the compiler, while compiling test.scm, sees no
syntax declaration of `without-exception', and therefore assumes that
`without-exception' is simply a top-level variable.
A simple workaround is to use `(include "woe.scm")'. I don't know the
full details, but my understanding is that unlike `load', `include'
causes the compiler to look for syntax declarations in the included
file.
Another solution (though guile-specific) is to make woe.scm a guile
module, and to use `use-modules' to import it.
Best,
Mark
