When I think about this issue in different terms I think it makes more sense. No matter how perfect my code I find myself interfacing to things like MySQL where it is happy to return nil when it means an empty string.
someValue ifNotUsefulUse: [ defaultValue ]. but then the question "what does useful mean", at which point it becomes easier to define clearly what is not useful i.e. someValue ifNilOrEmpty: [ defaultValue ]. If I had known this call existed I would use it much more because b := someValue ifEmpty: [ defaultValue ]. doesnt work (see earlier discussions on squeak-dev) regards Keith _______________________________________________ Pharo-project mailing list [email protected] http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project
