With Debian 2.2.4, this causes a compilation failure:
(eval-when (expand) (current-language 'scheme)) $ guile -s main.scm ;;; note: source file .../main.scm ;;; newer than compiled /home/rlb/.cache/guile/ccache/2.2-LE-8-3.A/.../main.scm.go ;;; note: auto-compilation is enabled, set GUILE_AUTO_COMPILE=0 ;;; or pass the --no-auto-compile argument to disable. ;;; compiling .../main.scm ;;; WARNING: compilation of .../main.scm failed: ;;; In procedure struct_vtable: Wrong type argument in position 1 (expecting struct): scheme I wondered if that was expected.
