Updates: Status: FixProposed Labels: Milestone-1.3 Comment #3 on issue 3769 by nicolas....(a)gmail.com: Printing an object depends on #isKindOf: http://code.google.com/p/pharo/issues/detail?id=3769 Name: SLICE-Issue-3769-remove-FakeClassPool-nice.1 Dependencies: Morphic-nice.875, SimpleMorphic-nice.22, Deprecated13-nice.10, Tools-nice.574, System-Text-nice.154, System-Tools-nice.44 remove FakeClassPool because it does not serve any useful feature. Rather than testing an evaluation result for (FakeClassPool) kind or #failedDoit, it is better and simpler to use the ifFail block provided in Compiler evaluate message.
