seems your template isn't working:
scheme@(guile-user)> (load "gvector.scm")
;;; note: source file
/Volumes/Mojave/Users/mattei/Dropbox/git/library-FunctProg/gvector.scm
;;; newer than compiled
/Users/mattei/.cache/guile/ccache/2.2-LE-8-3.A/Volumes/Mojave/Users/mattei/Dropbox/git/library-FunctProg/gvector.scm.go

;;; or pass the --no-auto-compile argument to disable.

but things go well if i remove module part and add:
(use-modules (oop goops)
(oop goops describe))

scheme@(guile-user)> c2
$1 = #<<gvector> 109e82500>
scheme@(guile-user)> (describe c2)
#<<gvector> 109e82500> is an instance of class <gvector>
Slots are:
v = #(#<unspecified> #<unspecified> #<unspecified> #<unspecified>
#<unspecified> #<unspecified> #<unspecified> #<unspecified>)
length = 0
probably a module issue.... but i never use them with this Scheme
otherwise things go well (in other file ....)
