At the C level, that seems somewhat ambitious. :-) > I don't know much about the implementation of the GOOPS objects, but I > suspect that they would also require some means of serialization The (oop goops save) module implements parts of a serialization framework. When GOOPS is loaded, any Scheme object is a GOOPS instance, so one could define methods to serialize any type of object.

Thanks, Ludo’.
