'From Squeak3.10beta of 22 July 2007 [latest update: #7132] on 24 July 2007 at 8:52:39 am'! "Reporter: Damien Cassou Summary: 0006575: New compatibility messages for TraitBehavior Description: TraitBehavior contains compatibility messages like #superclasses, #instVarNames... This helps tools to work with traits without changing everything. The attached mcz provides: - TraitBehavior>>#allSubclasses - TraitBehavior>>subclasses (pushed up from TraitDescription). Since these methods do not override anything and only returns new arrays without any computation, the fix can be considered safe. Additional Information: "!
