[Pharo-dev] problem with become:?

Hi, If I execute the following code in the latest Pharo image: Object subclass: #A instanceVariableNames: '' classVariableNames: '' package: 'AA'. Object subclass: #B instanceVariableNames: '' classVariableNames: '' package: 'AA'. a := A new. b := B new. a become: b. a class ==> “A". In a pre-Spur image, I used to get “B”. Is this a bug, or is there a change I am not aware of? Cheers, Doru -- www.tudorgirba.com www.feenk.com "Things happen when they happen, not when you talk about them happening."
