Hi,

Jean Abou Samra <jean <at> abou-samra.fr> skribis:

> OK, understood. How about adding comments and documentation?

That’s a good idea.  Applied with minor tweaks and a commit log.

Thanks!

Hi guilers, here's a short bash session.
Why would the first bash call to "guile s.scm" work, but not the second one?
guile-3.0.7 on ubuntu.

============================
$ cat s.scm
(format #t "~f\n" 2.5)

$ guile s.scm
;;; note: auto-compilation is enabled, set GUILE_AUTO_COMPILE=0
;;;       or pass the --no-auto-compile argument to disable.
;;; compiling /home/chris/s.scm
;;; compiled
/home/chris/.cache/guile/ccache/3.0-LE-8-4.5/home/chris/s.scm.go
2.5

$ guile s.scm
