Hi, have you tried define-type:
<syntax>(define-type NAME TYPE)</syntax> Defines a type-abbreviation {{NAME}} that can be used in place of {{TYPE}}. Type-abbreviations defined inside a module are not visible outside of that module. _______________________________________________ Chicken-hackers mailing list Chicken-hackers@nongnu.org https://lists.nongnu.org/mailman/listinfo/chicken-hackers
