Hello Sandra, The above program uses the procedures provided by the "s" egg at expansion time, so you need to load and import them at the syntax level: (begin-for-syntax (use s)) Or, in newer CHICKENs: (use-for-syntax s) The reason it worked with 4.7.0 and not with 4.8.0 is that this is really a bug: at compile time, procedures imported for runtime should not be available unless they're explicitly imported. That's the entry in 4.8.0's NEWS: "Fixed a bug that caused imported identifiers to leak into the macroexpansion/compile-time environment" Cheers, Peter -- http://www.more-magic.net _______________________________________________ Chicken-users mailing list Chicken-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/chicken-users
