Re: GOOPS question

[Damien Mattei]

juste understood LOL :

scheme@(guile-user)> (use-modules (gvector))

scheme@(guile-user)> (use-modules (oop goops))

scheme@(guile-user)> (define c2 (make <gvector>))



needed to load all the modules by hand even if used already by gvector, in
gvector definition, confused....
