I think you can avoid using 'equal' word when describing a #== comparison. It can be explained as 'test whether comparands are same object or not' while #= is test whether two objects equal or not. Also keep in mind that #== optimized by compiler. So , even if you override it in some class, it won't behave differently. And #=, of course, can be implemented in any way you like. One of interesting example: = anObject ^ false saying 'i am not equal to anything' :) > Johan > _______________________________________________ > Pharo-project mailing list > Pharo-project@lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project > -- Best regards, Igor Stasenko AKA sig. _______________________________________________ Pharo-project mailing list Pharo-project@lists.gforge.inria.fr http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project
