Adding methods to a global generic functions means taking the function object and adding a new method to the list of already existing ones. In the lowlevel macro system, `define-method' checks whether the toplevel variable has a binding, and if not, installs an (empty) generic in it. With syntax-case the situation is different. Due to peculiarities of the module system (definitions may not be scattered through a module, but must appear at the start, like in local/lexical `let' bodies), the implicit definition used by `define-method' doesn't work. The syntax-case version of `define-method' assumes a generic has already been installed under this name, i.e. you have to do it manually, like this: (define-generic clean) Just put it before your first method definition. cheers, felix _______________________________________________ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users
