Hello, when I try to use guile-irregex, I am presented with a notice about auto-compilation: $ guix shell guile guile-irregex -- guile -c '(use-modules (rx irregex))' ;;; note: auto-compilation is enabled, set GUILE_AUTO_COMPILE=0 ;;; or pass the --no-auto-compile argument to disable. ;;; compiling /gnu/store/0dsldjpjkb5jhmbp9v7hqh4g99abw4d4-profile/share/guile/site/3.0/rx/source/irregex.scm ;;; compiled /home/wolf/.cache/guile/ccache/3.0-LE-8-4.6/gnu/store/28kbndqfrzblr3jdin9i28nwqmy6vsys-guile-irregex-0.9.6/share/guile/site/3.0/rx/source/irregex.scm.go I did not expect that and I am pretty sure that should not happen. The .go file seems to be present in the store, so I am unsure why it is not loaded. W. -- There are only two hard things in Computer Science: cache invalidation, naming things and off-by-one errors.
