[Pharo-dev] strange code in RBRefactoringTest

[Christophe Demarey]

hi,

Does anyone knows if there is a particular reason to write this kind of code 
(snippet from RBRefactoringTest>>setUp

        assoc := RBRefactoringManager classPool associationAt: #Instance
                                ifAbsent: [RBRefactoringManager classPool 
associationAt: 'Instance'].
        manager := assoc value.

Thanks,
Christophe
