However when I try to create an instance of the class using (use-modules (oop goops)) (define test (make )) guile raises the following exception: No applicable method for #< initialize (9)> in call (initialize # ()) Searching in guile's source I do find in in the file goops.scm the line (define-standard-class ()). So my question is why the class is predefined while it is not implemented? It is only because implementation is not yet finished? Should I design the class myself? Thanks for your answers!
