Footnote (29) of this page <https://www.gnu.org/software/guile/manual/html_node/Class-Definition.html> of the manual mentions that the complex is a predefined class in GOOPS. However when I try to create an instance of the class using
(use-modules (oop goops)) (define test (make <complex>)) guile raises the following exception: No applicable method for #<<generic> initialize (9)> in call (initialize #<instance 7fb5dc535680> ()) Searching in guile's source I do find in in the file goops.scm the line (define-standard-class <complex> (<number>)). 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!
