A situation not mentioned above where you may prefer something else, even if not breaking hygiene, is when your macro would be better off written in procedural style; syntax-rules' exclusive reliance on pattern matching sometimes leads to byzantine code. This will be obvious when you hit it. define-macro is not available in Chicken 4. Explicit renaming is supported by the core. Documentation on ER is available at http://chicken.wiki.br/man/4/Modules%20and%20macros#explicit-renaming-macros . The eggs and the Chicken core are good places to see working examples. _______________________________________________ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users
